[Making out with Natalie, Duncan sees her toy elephant Guppy staring at her]
Guppy
[talking]
What's wrong?
Guppy
Ah, you're not into it. What's up?
Duncan
I can't help thinking...
Guppy
Don't THINK, just get on with it!
Duncan
I'm trying to, but all sorts of stuff's spinning around my head!
Guppy
Look, mate, take my advice: you just got to switch THIS off!
[points at his head]
Guppy
D'you think I would be able to do this if I thought about it? Huh? Do you, huh?
[walks on air, then thinks about what he just did and falls with a holler]
Duncan
I know, but it's all a bit...
Guppy
[climbing on the bed]
A bit quick, yeah! Yeah, a little bit too easy?
Guppy
Then this was so easy for you, and EVERY OTHER...
Duncan
I don't want to think about THAT, but I can't help it!
Guppy
Well then, you've got to stop!
Guppy
Yeah, yeah, just stop immediately! Tell her that you respect her far too much to continue having sex with her!
Guppy
COURSE NOT, YOU MUPPET! Just enjoy it!
Guppy
Don't mention it.
