I'm going to go with Christina here. I remember skipping school that day and watching the launch on TV. I remember the Christina jokes afterwards. Here are the two that come to mind:

What did Christina McAuliffe say to her husband just before going on the mission? "You feed the dogs and I'll feed the fish".

What color were Christina McAuliffe eyes? Blew.

That's all I can remember now, feel free to add any I forgot. Good Times.
