I Have a aunt who is pretty fat, especialy her bottum.
She played a little scene with an other sister during de servicemeating( don't know the exact name in english). she was sitting at the table with the other sister on the platform playing someone who was given biblestudy.
At the end of the scene, when she wanted to stand up, but the chair got stuck on her and she could not get it of her behind.
Now my aunt's got a good sense of humor and she stood up turned her behind with the chair still on it in the direction of the hall and started to shake her bottom...The whole gongregation could not stop laughing.
