In college, I got the following line:
"Wanna come up to my room and see my snake?"
--Yes, I was drunk and totally oblivious to how ridiculous it sounded. Apparently the friends I was with thought it was hilarious, though.
--So yes, I responded with "cool! a snake!" and went up to his room. (My sister had allergies when I was a kid, so we had weird pets, including several snakes.)
--Yes, he actually had a snake in his room.
--IIRC, we didn't end up fooling around. I think he was a little taken aback that I was actually enthusiastic about hanging out with his snake and more interested in it than his "snake."
