OMG - i cant believe someone actually went and said it. I spent my whole childhood being called vegetables only to end up working at a bloody school and get it starting all over again.Worse thing is every single bloody kid that says it thinks they are being original and truly funny - my grandad got exaclty the same thing all his life!!
OR! Sticking with the Vegeta thing, you could combine it with your name to have the "Wez Vegeta-bles" :P
