Two gangsters are about to break out of prison. The first one jumps off a wall into a trash container.
The guard shouts, “Who’s there?”
Gangster replies, “MEOOOOOOW!”
The guard is relieved, “Ah ok, just a cat.”
Then the second gangster jumps.
The guard gets suspicious, “Hello, anybody there?”
The second gangster yells, “Nah, just the cat again!”
