I went with the Super Adventure Box title for a long time, "Honors in Applied Jumping" I think it was. Kept that one because of how much fun I had with SAB. Eventually switched to "The Extra Life" with the hope that it might encourage others to donate, and I've been using that since.

Though I think there was one from season 3 that I used for a short while too that was a bit difficult or time consuming to get, can't quite remember it though.
