One night, as a drunk man went up the stairs to go to bed after a long night fell as he was half-way up. It so happened that there was a glass bottle in the back pocket of his jeans, so when he fell, he cut his bum.
The next time he tried, he got up. He went to get a bandaid and went into the bathroom to stick it on. He finally got it stuck on.
The next morning, when he recovered from his drunkness, he felt his bum, to find that the bandaid wasn't there anymore.
He decided to finally get up and out of bed, and as he went into the bathroom to brush his teeth and wash his face, he saw a bandaid on the mirror!
