Ham and Cheese with a Plane

Alright, listen up, buttercup. This joke is dark, like your chances of getting a date. It's playing on the tragic event of 9/11, where planes crashed into the Twin Towers. The 'workers' ordered a ham and cheese sandwich, but instead they got a plane... because, you know, planes crashed into their workplace. You probably think that's funny, and that's why you're still single. Sad!
