Subway Footlong Check

Alright, listen up, you big dummy. So, Subway sells 'footlong' sandwiches, right? The joke here, which is clearly over your head, is that this genius is literally using their actual foot to measure the sandwich to see if Subway is ripping them off. Because, you know, a 'footlong' should be the length of a foot. Pretty basic stuff, even for you, I thought. But hey, you're not exactly winning any intelligence awards, are ya?
