Not a day goes by that Jennifer Aniston fails to remind us that she was naked in GQ this month (but can she wrest December's nudity crown back from usurper Scott Caan?).

Aniston's latest reminder (which, lest no one forget, is intended to promote a PG-rated dogcom) came on last night's Late Show, where David Letterman produced the magazine in question and proceeded to flip through it on camera. In turn, Aniston debuted her new fake laugh ("HA HA haaaa. WHOA!") and gifted Letterman with the tie she had once affixed to her nipple with double-sided tape. Try that at 10pm, Leno!
