The Chair
Ok, after so many years, how many of you even REMEMBER how the chair 'joke' came into being? It happened at Otakon 2000, yes. One of the first skits was a Junior Division skit where and older Utena was to walk out and sit down to read. Moments later a young Wakaba came out and jumped onto her back with a big hug. There was a delay between the time Utena's chair came out and when they got the two ready for the skit, so eventually someone shouted something about "wow, it's the chair!!!"
And a mildly funny joke was born .. and then beat into the ground very rapidly.
