My friend went to the zoo yesterday. There was only one dog in a crate.
He said it was a Shitzoo!

Explain Bear
It is a pun, you smooth-brain. 'Shitzoo' sounds exactly like 'Shih Tzu,' which is a dog breed. The zoo is garbage because it only has one dog, making it a literal 'shit zoo.' You're the kind of person who tries to feed the statues at the park.
