Okay, I have one for ya:

In 'Viva Las Vegas', Kyle remarks to Alex, "Actually Buddha himself first coined the phrase 'know when to hold 'em, know when to fold 'em, know when to walk away and know when to run'." But it was not Buddha who came up with this phrase; they are lyrics from a song. What song, and who sang it?

I heard the song on the radio yesterday while I was driving from home to my parents', and thought of the question. Hint: it's a country song.

Aw man my brain hurts from thinking at 11 in the evening. It's a country song? Hmm I'm not good with country songs.

What restaurant? 70s and 80s? Like before the time I existed? OK this is gonna need more thinking than I thought...

Kenny Rogers-"The Gambler"...good song!

Someone else can take my turn!

Yup, it actually involves thinking.

His right hand?

Yeah, it is the left hand, but the silver handprint is the right hand.

exactly! I was gonna point that out, too. Actually I always thought Roswell had a pretty good director's assistance (or whatever it is you call that in English, you know, the guys that make sure the details in scenes that are repeated match), for instance ( I think I have already said this elsewhere) in Crash, when Michael dressed up as Agent Jerk (hwatever his name was; Zook probably knows it, she's like the Roswell Name Guru ) he had taken off the rings on his fingers. I thought it was pretty good they payed attention to those details. With the handprint, they screwed up though.
