Advertising Only Possible in the Summer (at Least in Boston)

This morning, I saw three guys advertising Men's Wearhouse's National Suit Drive. And how were they advertising this? By standing on the corner of State St. and Broad St. in boxers, shoes, and ties. As I said to them as I passed, this weather (it's currently 82 F with an anticipated high of 86) is at least conducive to this type of advertising. Much better than December, one of the guys agreed.
