My favorite JCD and Adam interaction from the show must have been around 10 years ago, and went something like this.

Adam: You know when you you clamp your dick between the thighs ....

John interrupting: I can't do that!

Adam slightly flustered: Why?

John: Because it's too damn big!

Adam: I walked into that one!

I wish I could find the clip. That's what I call thinking on your feet!
