In the classic Popeye cartoons, the sailor is constantly squeezing open a can of spinach with his bare hands and then getting into fisticuffs with Bluto and other cartoon baddies. 

What the cartoons don't show are the digestive consequences of eating an entire can of pre-cooked spinach without even chewing. This is where Pete Holmes comes in, giving Popeye a reality check. I'm sure you can see where the gag is going, it's a total gas! *badum dum*  ...I'll see myself out.
