dream with joke

I dreamt I had decided to become a stand-up comedian, and I was writing a skit around how I would take on a life of crime. In the skit, I had been given a password that would allow me access to a criminal den. The password was 'Mumbles'. I knocked on the door and said 'Mumbles'. The person on the other side opened the door and said, 'Yes?'

It's not often you get actual jokes in dreams.
