My vote is on Eutychus!

Sometimes life is so great you just gotta muss up your hair and quack like a duck!
Darius Rucker. Yes, that’s Hootie. I don’t care. All he’d have to do is sing to me, and I’m his.
A few more:
Patrick Stewart–I love his voice…and my dad has done that combover thing for years–It’s nice to see someone that doesn’t mind being bald.
Definitely Scot Bakula–I used to watch Quantum Leap all the time…and it wasn’t because of the fascinating plot lines!
I think Bono is attractive since he cut that long stringy hair…Some men just don’t look good in long hair.

The guys in The Full Monty.
voguevixen, I agree - David Letterman is sexy!
I have erotic dreams about a few different celebrities. The two who would fall in the “surprisingly attractive” category are David Letterman and the artist formerly known as Prince.
I figure anyone who sings about sex as much as TAFKAP must know what he’s doing in the sack. But if I ever met him in real life, I don’t think he’d be as sexy. I’m 3 inches taller than him and I’m sure I outweigh him.
That would be a turn-off.
Most common question I ask: “What?”
Most common question I get: “Are you really hearing impaired?”
Falcon… DAVE MATTHEWS! Ohmigod he is so sexy… did you see the VH1 Storytellers he did? Flirting with the girl in the crowd, talking about being naked in the hotel hallway…
::drool::
Second the Dennis Quaid but I bet he doesn’t count.
Drain Bead, I agree on Beck. Something about ruddy-cheeked guys! Don’t get me started.
How about the red-haired guitarist (or bassist) of the band Lit? In their video for “My Own Worst Enemy” they’re dressed in 70s retro stuff and this guy is just sexy.
But I’ve got a thing for redheads, too.
Canthearya - No, my cable went out the day it was supposed to be on! Oh well, gives me another reason to try and find it again, I suppose. However, he does his fair share of flirting at the concerts, and I’ve seen…7 so far. (No. 8 on August first! Woohoo!) He’s sexy, and the second he opens his mouth and starts singing…sigh.
And I never took a good look at the bassist in Lit - I was too much a fan of the lead singer. 
I have to agree with the votes for John Cusack, Dr. Drew, Dennis Miller, Adam Sandler, Anthony Edwards, Dave Matthews, Trey Parker, Michael Biehn, Dave Foley, and Beck.
The only other one I can think of at the moment is Josh Charles (he played Knox Overstreet in Dead Poets Society and is currently on the TV show Sportsnight).
I can’t believe I forgot this one. My only excuse is that I don’t find him surprisingly attractive, but other people are surprised that I find him attractive.
To put it this way: I am a college student, and I have exactly one poster up in my room (although I’m still waiting to get sticky-tack so I can put up my 12 Urban Legends poster). It’s Conan O’Brien’s milk ad. I love Conan. I love that growly noise he makes at pretty girls. I love his self-effacing sense of humor. Conan is completely adorable to me.
Okay, after seeing Dave Matthews live this weekend, I need to add one more person: Stefan Lessard, their bassist. Oh my, that man is gorgeous! (And he’s actually my age…hmmm…)
Shirley Ujest, you listed two of my all-time favorites - Anthony Hopkinds, and Liam Neeson. Anyone with a British/Scottish/Irish accent gets my vote, actually. It’s the whole voice thing. Sir Anthony once stayed at a resort where I work (as a secretary), and I had serious thoughts of dressing up as a housekeeper so I could just go clean his toilet, on the off chance of getting a glimpse of him. He’s adorable! His role as Frederick Treves in The Elephant Man, when his hair was still dark, is the best!
Robert Carlyle
Ewan McGregor
Gabriel Byrne
(I have a thing for the ritish/Irish/ Scottish accent…makes my knees buckle every time
The gene pool could use a little chlorine.
Sigh
Of course I meant British/Irish/Scottish
So much for making a good impression
The gene pool could use a little chlorine.
John Goodman…love his sense of humor, incredibly sexy
Bill Pullman
Scott Bakula
Patrick Stewart…he makes me melt
Dennis Miller…his sarcastic cutting wit is wonderful.

Patrick Rafter. Sure, he’s not surprisingly attractive (to be honest, he’s the most attractive man I can think of in sports today), but damn, the man is hot. Aussie too, I think.
A younger Walter Koening (Chekov on Star Trek). All the other celebrities I can think of are conventionally attractive. But I like thin unmuscular nerd boyz in general.
Incidentally, a useful word for you folks would be jolie laide: a woman who is attractive although not conventionally beautiful. Literally, a beautiful ugly woman. The masculine form is joli laid.
Barry Pepper!
And did Robert Sean Leonard play a Nazi? Not in Swing Kids, if that’s what you’re thinking…
I agree with many of the men listed, but you forgot Ben Folds!! Goodness…heheheheehe. ben!
also: Fran Healy(from Travis), Damon from Blur, Edward Norton(goodness), the fragile guys of Silverchair, Jonathon Rhys-Meyers(I seem to like skinny boys), Ralph Fiennes, Casey Affleck, Wes Bentley(from American Beauty), I could go on forever, but I’ve embarrassed myself enough…I forgot the Edge and Larry from U2. Of course, I like Bono the most. hehe
Jerry Lee Lewis (back in the day)
Van Morrison
Beck
Ewan McGregor
Johnny Rotten (shut up! he’s damn sexy)
The guitar playing Robinson brother from the Black Crowes (Rich, I think)
Iggy Pop
Thom Yorke
I would totally rearrange my life for Kyle Chandler from the TV show First Edition. Those eyes, that mouth…sigh…
