squirrely
I just always laugh, thinking about a bunch of no good squirrels, standing around in leather jackets, smoking, whistling at chicks walking by.
I love describing people as squirrely.

and I agree, UNDERPANTS is one of the funnier words in existence.

My friends and family LOVE the way my mom, who’s got a beautiful Southern accent says the word “boys,” as in: “You shouldn’t be stayin’ up in that apartment with them bhoaees.”
My mom also can tear up some Spanish, and Southern accents and Spanish just DON’T mix. You know how Spanish has the “ll” sound that is pronounced “ellye”? Well anytime she comes across that “ll,” she pronounces it like a regular “l”. So when she in her beautiful Southern drawl refers to a restaurant, like Casa Gallardo, it’s absolutely hilarious. Casa GaLARdo. Or like the word “llegar,” which means to arrive. “Leygahr.” Oh, just PRICELESS! 
Oh, and I have to add my vote for “panties.” That word, especially when pronounced in a Southern drawl is just too too funny.
Gosh, now that I think about it, I love just about anything that’s pronounced with a Southern accent. It’s beautiful, and it’s funny.
Well, that’s all for now. I’ll be thankin’ 'bout whut else stikes my fancy.
Y’all have a nice day, y’hear?

I think for “underpants” to have its full effect, it must be pronounced “unna-pants”, and it must be said as loudly as possible.
UNNA PANTS!!!
Inchoate - it just sounds dirty.
Turd - what a happy sounding noun.
Titmouse.
Hootie, as in Hootie and the Blowfish. Say it a bunch of times…hootiehootiehootiehootie! It’s right up there with boobies. Boobiesboobiesboobiesboobies!
Chimichangas. My boyfriend and I have a little ongoing joke whereupon one remarking, say, “Why don’t you do the dishes?” the other will reply, “I’ll do your dishes!” So, one day he said something about chimichangas, and I replied, “I’ll chimi your changas!” I tinkled my pants over that one.
Oh yeah, “tinkle”, too.
Platypus.
Hehe.
Eleemosynary. Though it’s not a word one encounters in the wild very often. Sam Rayburn’s comment during the Watergate hearing’s that he didn’t regard the CIA as an eleemosynary organization won it a place in my regard for all time, but it still brings a giggle to my lips.
Sigh
Time to go home. Missed that even after I previewed.
ok I’ll elaborate a little more because I want to. What makes them so funny to me was back in 1990 I got them mixed up pronunciation wise. I began saying spacific and pecific. I knew I was saying them wrong and if I really tried and spoke real slowly I could say them right but in normal conversation I would always transpose them. It was so freaking annoying. After about a week I finally got them straight.

You are not alone brother Raziel.
“Panties”
“Yogurt” and “Spam”
I think I’ll throw in the word “cockpit”, I mean seriously the actually meaning is really dissapointing considering the two words that make it up. Now if women would start naming their “parts” like men do I think we have found a hands down winner.
Swed.
My brother was doing a crossword puzzle and the answer was supposed to be awed, but all he could come up with was swed. <chuckle> (That’s almost a giggle, right?)
But my all-time favorite has to be…

Just the word “giggle”. It makes me think of someone with a jiggling fat belly. There you go, another one, “jiggle”.
Regina.
Capital city of Saskatchewan.

It’s even more disappointing when you think about this: What does one usually find in a “cockpit”? That’s right, a “joystick”.
Honeybunny. I challenge anyone to say this word aloud without smiling and/or giggling. A friend and I tried this for the entire year we had a science class together and couldn’t do it.
