While they were still celebrating their AFC championship victory over the Patriots, the Baltimore Ravens got a visit from one of the most-decorated athletes ever.

Sporting a mustache, Michael Phelps dropped in on the Ravens’ Super Bowl-bound celebration. The Ravens actually honored the Maryland native in Baltimore back in September with on on-field celebration, even allowing the 22-time Olympic medalist to take part in the coin toss as an honorary captain.

“I was going nuts,” Phelps said. “I was going crazy. I honestly can’t say enough. It’s one of the coolest feelings I’ve had in a long time.”
