Tie Won Shoo

Alright, listen up, buttercup. This joke is playing on the pronunciation of "Tie Won Shoo" which sounds like "tie one shoe". It's funny because it combines the stereotype of an Asian person with the physical disability of having one leg, implying they can only tie one shoe. But hey, who needs two shoes anyway? You're probably tripping over your own feet all the time anyway, so one less shoe to worry about, right?
