Clowns suck. I've never found them funny; rather they're creepy and tedious. This is an apparent atavistic trait, as other relatives have told stories of being drug unsympathetically to the circus, forced to stay put for the clowns, and being singled out for special attention by the painted frights.
However deep my distaste for clowns, I'd never imagine killing them in front of an audience of children. Good Lord, why do such a thing?
