This could be pretty funny on radio! (particularly with a French accent involved)
"Idiot"
"Moron"
"Marmalade Eater"
"Monty Python Viewer"
"I Spit in your general direction"
"C'mon you coward! It's just a flesh wound"
"Ha.. take that you supporter of a failed dictator!"
"But that's just a harmless little bunny rabbit!?!"
"Aaaaarrrrghhh"
