There's room for a few extra, me thinks...
* a clapping hands one to show appreciation.
* a steam coming out of ears one to show frustration.
* a shaking head on to show disbelief.
* a head in sand one for when somebody ain't listening.
* a fire truck one to put out flames.
* a peg on nose one to warn of cuuried cabbage and other gas attacks.
* a blindfold one for when somebody can't or doesn't wanna see.
Oh, and while we're on the subject!! If HG has a pizza one, I wanna bowl of curried cabbage one.
