My "other" is hurricane glasses from the Hard Rock. Not a collection officially, but these were picked up during my travels. The rule is that I have to have at least one of them at the restaurant. The second rule is that it has to be during a business trip and the company has to pay for the glass (since they put it on the bill as a hurricane for $10 along with lunch).

They are now lined up above the kitchen cabinets. I then realized that
a) I have been too many places
b) I drink too much

(actually b is not true, I make an exception for the HR hurricanes).
