I Am Allergic To Casbahs

I am allergic to cats. I'm so allergic that when I order hamburgers, I request that they hold the C-A-T-S-U-P. Then I ask if I can borrow a bottle of K-E-T-C-H-U-P, with which I liberally douse my burger.

Coincidentally, this is a great way to get yourself stabbed in the neck by an angry short order cook.
