Not an accident but a funny moment with a character at Donald's Breakfastosaurous.
I was at WDW with my cousin and his potty training 2 year old son. Just as we sat down to eat Matthew announced that he had to go 'potty'. A few minutes later he comes flying across the restaurant, smack into Donald Duck, and then right into me yelling all the way " I just went poopy in the potty!!!" Donald and the handler came running over and Donald made a big deal about it by jumping up and down and patting Matthew on the head. A manager came over to find out what was going on. Again, Matthew proudly said " I went poopy in the potty!" The manager replied, " Well you know buddy, I did that today too!" He then had Donald Duck sign a picture and present it to Matthew. Matthew still talks about that day.
