How funny is zzzzz?! I didn't realize before tonight but Mummy was talking about beezzzzz and zzzzapping things and I couldn't stop giggling! Even when I was a bit upset after my bath a few zzzzzzzzzz cheered me right up. Seems to me that more zzzz in a word makes it even funnier - zap is amusing, but zzzzzzzzap is HILARIOUS!
