Lady Friend (trying to whistle through a tiny straw) - I can't breathe in that hole.
Me - That's what she said.
WINNER! Best That's What She Said ever. I might have to retire from saying it, now. I think both the irony of the horrible joke as well as the quest to find the greatest TWSS ever have both been achieved - therefor I am officially retiring from using the phrase, "That's What She Said".
...at least for today.
