One of my nephews is so funny. Remember Mickey Mouse Christmas w/ Chip N' Dale? We were singing some Xmas caroles around the fireplace and at the end of Deck the Halls, he started howling just like Pluto did. Since it is already Xmas I could not put "Do not open till Xmas tape on his mouth."
How's this for a T-shirt? Front: Bill Cosby wearing headphones with the caption "Now I can't hear you say 'stop, no and don't'!'" On the back he will be in a orange jumpsuit with tape across his mouth with the caption "now you can't hear me say 'stop, no, & don't' either"
