I found this on another forum. Some of the responses were genius.
In a perfect state, it would go something like this:
person one: love is like a classical melody
person two: if you end your performance too quickly, your audience will be dissapointed!!
person two: you're like a mine in a potato field
person three: not nearly as fun to find as a cake
...and so on
I'll start. Women are like murlocs.
