The other night I dreamt that I was a stand-up comedian and electronics salesman at a local furniture and appliance store. Between sets, I would thoroughly hose down the furniture before the next audience would sit down. I could tell I was famous by the way everybody looked at me.
A new audience comes and takes their soaking wet seats and waits for the jokes to commence. I start in with my best joke right away, "...so I said to my wife, 'shut up and get me some toast', and she said to me, 'why do you talk to me like that when you never speak to anyone else that way?' So I said, '...' I said, '...'"
I knew the punchline earlier in the dream, but I just couldn't come up with it. I was too tired to care.
