Razor blades and a really stupid woman

I’ve been using razor blades in my show for the past 12 years without incident.

At last night’s show, an audience member insisted that my blades weren’t sharp (after I had just proven to everybody that they are very sharp).

She grabbed one and quickly sliced it across her own wrist – REPEATEDLY.

While she was slashing away – and BLEEDING – she kept insisting that it was “not that sharp.”

Would a comment such as “I sincerely hope that dumb bitch dies so she can’t breed” be too harsh?
