Sawcon and Ligma

Alright, listen up, buttercup. This joke is like a trap, see? The dude tries to trick the Sensei with a "Sawcon" joke, setting him up to say "Saw con deez nuts." But the Sensei flips the script and acts like he knows about "Ligma," which is another fake disease name used for a "Ligma balls" joke. Basically, the first guy gets played at his own game. It's all about the element of surprise, which is the only thing you're good at... surprising everyone with how little you know!
