I'd Like to Buy an Interrobang, Pat

[gnomi]

There's a new advertising poster I've been seeing all over the Red Line for the boston.com classified section. It has six icons on it: a blue circle with a white suitcase on it, a dark green circle with a car on it, a red circle with a white house on it, an orange circle with a white chest of drawers on it, a purple circle with a white doglike thing on it, and a lime green circle with an exclamation point on it. I have therefore decided that they're touting the ability to buy the following from boston.com classifieds:

-- Luggage
-- Cars
-- Houses
-- Furniture
-- Mutant pets
-- Punctuation

Seriously, though, the first five I can figure out, kinda: travel (or maybe it's a briefcase and it's for jobs), cars, houses, furniture, pets. Those all make some sort of sense. But I can't figure out what the ! is all about.

And I don't want to give Boston.com any satisfaction by going there to find out what they might be trying to sell with that exclamation point.
