Marlon Humphrey and other Ravens want to learn how to swim. Luckily for them, they landed the best teacher available: Michael Phelps.

Several Ravens – Ronnie Stanley, Kyle Hamilton, Charlie Kolar, and Marlon Humphrey – filmed a humorous video Tuesday, imploring Olympic swimmer and huge Ravens fan Michael Phelps, winner of 23 gold medals, to help teach players how to swim.

Michael Phelps, the most decorated Olympian of all time, certainly knows a thing or two about swimming techniques.
