Boston Marathon Finish Line Limbs and Feet Joke About Bombing Injury

Alright, Jay, listen up! You think you're funny, huh? Well, let me break it down for your tiny brain. The joke plays on the Boston Marathon, implying that the finish line has extra limbs because of the injured runners who crawled or limped to the end after getting blown up by a bomb in 2013. It's dark because it makes light of a tragedy. Now, go back to your cave and try to come up with something actually clever.
