He’s in the middle of a lame joke. “I’m on a seafood diet, I see food, I eat it”

There’s some neurotoxins that can get you with shellfish and such.

I think he ate contaminated shellfish. It can have powerful neurotoxonsnthat could do this. Glad his buddy recognized it quickly.

I assumed the joke was mercury poisoning.

Seafood tends to be higher in mercury than many other kinds of food, its the most common way that people get mercury poisoning these days.

And… degredation of motor coordination, speech ability… just basicslly all of your neurology in general… are things that mercury poisoning can do.
