My mom was giving her one of her daycare kids bath. S/he was probably about 4. S/he was playing in the water, when S/he suddenly passed gas. S/he SHRIEKED for my mom, and she came running into the bathroom. The poor kid was white with fear.

"Mabel.." s/he says, in a shaking voice, "There are noises in my bum!" S/he was almost in tears so mom didn't want to laugh, but she said it was SOOOOO funny!!!

(Note - I can't remember which kid did this, hence the "s/he" )
