One time I was drunk and rode my fixie to class, then walked back to my apartment (this was in San Francisco). The door happened to be ajar and I entered seeing that my bicycle was missing. I blamed both of my roommates and they were very sad. I went to class the next day and found my bike locked up just where I left it.
I didn't drink for a while after that, and gave my roommates all my good beers to make up for it!
