You're probably familiar with the phrase "That's what she said," and its uses. Adding those words to almost anything said by someone else can turn the original comment into a sophomoric sex joke. (Click here for some Star Wars-related examples.) It's a routine that -- IMHO -- gets tired quickly, and is rarely incredibly funny, but...
Having said all that...
One night I was with a group of friends, male and female. We were congregated on one friend's back porch, having a few beers, when someone made some innocent comment. Someone else followed up with "That's what she said!" which made a joke of the previous sentence.
A guy named Randy made a remark to the effect of, "You know, nine times out of ten, you can add 'That's what she said' to anything someone else has said, and it ends up being really funny!"
Most of us nodded in agreement. And then, after a pause, someone took the conversation in a totally different direction. I don't even recall what he or she said... but Randy followed it up with "That's what she said!" and in this case, it was such an unfunny non-sequitor that absolutely no one laughed.
I shrugged. "I guess that was your 'tenth time,' Randy," I told him.
Randy just grinned, and replied, "That's what she said!"
Thanks for your time.
