Is it a sarcame to say "get a sesame cut in half"?

(Aside to the important work we are doing here: the bagel places are hurting because of the Atkins diet. Slender waifs want their bagels alright but they want scooped out. That's right. "Can I get a sesame cut in half and scoop one half and filled with the low-fat veggie tuna salad. Oh, and a Diet Coke." They do not eat the other half.)
