Sweet insults:

Any similarity b/w you and a human is purely coincidental.

Are you always so stupid or is today a special occasion?

I'd like to kick you in teeth, but why should I improve your looks?

Brains aren’t everything. In fact in your case they’re nothing.

Keep talking. Someday you'll say something intelligent.

Dont you love nature, despite what it did to you? :-):-D...
