This is a man wearing a sealed fishbowl over his head and breathing out of some sort of homemade respirator. Why? The same reason men do anything -- to gain the attention of the opposite sex. Just look at those two ladies in the picture. You know what they're thinking? I'm so f***ing glad we're lesbians.

Thanks to Jeremy, who used to wear a mouse cage on his head until they started clawing his eyeballs out because I told them there was cheese in his brain.
