I’m not Dirk Diggler
Did you play Wesley in Buffy?
Nope, ain’t no Alexis Denisof
I highly recommend it. I think anybody who has seen it would. Absolutely wonderful film.
Do your nephews often go on adventures in search of treasure with your Scottish uncle?
Did you play a character on the original CIS?
Do I read about your sound in my history book?

Have you played a government agent on two different TV shows?
yes, that was a typo.
Now let’s head back to the world of sports, since I want some more DQ.s 
Are you a Russian top tennis player?
Did you win the Australian Open in 2008?
Too late - **Wash **correctly guessed that I was David Duchovny, who played both FBI Agent Fox “Spooky” Mulder on the X-Files and DEA agent Denise/Dennis Bryson on Twin Peaks.
Or maybe it was a shot in the dark but I couldn’t find any other guy who fit the bill :). So, congrats Wash !
Can we call it an educated shot in the dark? Duchovny popped into my head as an actor mostly famous for TV roles, but I was really just hoping you weren’t a Twin Peaks fan and Den(n)is(e) would help me to a DQ.
Either way, huzzah, I think this is the first time I’ve won a game on the Straight Dope!
However, I’m a little too busy to start off a game, so someone else feel free to take my turn.
Just to clear up a loose end:
I was referring to Bo Diddley.
Gah. I thought about him first, but didn’t think he’d show up in any high school history book. History is… older, y’know ? History’s when they didn’t have rock’n roll. Anything after that is just the past 
I even looked up the guy who blew the trumpets of Jericho 'cuz that seemed more like it :smack:
Ok, I’ll pick up the ball.
**JB **(yes, I’m using two letters this time)
Assuming J is first nam, B last name :
