Ulman made good on his wager with Prince George's County Executive Rushern Baker III as the pair, joined by Ulman's 7-year-old daughter, Lily, collected trash along Sheriff Road in front of the Prince George's Sports & Learning Complex in Landover while singing "Hail to the Redskins."
Ulman challenged Baker to wear a Ravens' Haloti Ngata jersey and declare Friday a "Purple Friday" in Prince George's County if the Ravens had won. Baker upped the ante, asking Ulman to don a Robert Griffin III jersey and perform community service.
The Redskins defeated the Ravens, 31-28, in overtime, at FedEx Field, which is located within eye sight of the Prince George's Sports & Learning Complex.
"I must admit, I left before the field goal. I knew it was going in," said Ulman, who shared a box at Sunday's game with Baker.
After arriving Wednesday in his Ngata jersey, Ulman was given a Robert Griffin III jersey by Columbia resident Ilana Bittner.
Ulman asked residents through social media this week for a Redskins jersey to wear, and Bittner's submission was chosen over seven others.
Baker said the mood in the box Sunday was tense as the game moved into overtime.
"I don't think I've been that nervous since I waited for my election returns," Baker said.
Baker offered Ulman a chance to cancel the wager with overtime looming, but Ulman declined.
"I was getting a little over confident when RGIII got knocked out. I didn't know the backup quarterback was so good," Ulman said.
