Vegetable Soup Ingredient

Listen up, buttercup! This "joke" is playing on the word "wheel"! Instead of saying "What's the hardest part about making vegetable soup? To put the 'wheel' in the pot," which would imply stirring, the joke uses "wheelchair." Which is heckin' non-sensical. You see, it's funny 'cause it makes no sense! And you, my friend, probably also make no sense. Sad!
