JEFF: I mean, where exactly do you take your socks off? My advice is to get them off right after your shoes and before your trousers… that’s the sock gap. Miss it and suddenly you’re a naked man in socks. No self-respecting woman with let a naked man in socks do the squelchy with her.

PATRICK: That’s your foreplay tip? Socks?

JEFF: Many men have fallen through the sock gap, Patrick. Under the sexual arena of earthly delight, there lurks a deadly pit of socks.
