"My girlfriend is turning 32 soon...
I've told her not to get her hopes up. "After all," I say, "we're only going to be celebrating it for half a minute." When she asked what in the world I was talking about, I pointed out, "This is your thirty-second birthday."
For the life of me, I can't figure why doesn't think this is hilarious. I keep making sure to remind her of it every time we are around new people. Hopefully if she hears the joke enough she will start to appreciate it."
This one is which I recently read and it took me some time to get it, but I find it funny :D
