If Heisenberg is right then lasers shouldn’t work.

Heisenberg, Goedel, and Chomsky were having a discussion.
Heisenberg says “we can’t know if it’s a joke”.
Goedel says “of course it’s a joke, but we can’t tell if it’s funny because we’re IN the joke”.
Chomsky says “of course it’s funny, it just hasn’t been told right yet”.
