In speaking with Lisa Salters of ESPN recently, Mahomes explained that he had done this with the help of his teammates who are not above making fun of his voice.
"If I'm ever getting too big of a head, they just kind of bring out the voice, you know — they try to mimic my voice," Mahomes said. "That's kind of gotten its thing in the locker room."
When Salters asked who imitated the voice the best, Mahomes' answer: Andy Reid, the Chiefs' head coach.
However, Mahomes said Reid would never do the voice in front of other people, so we will have to be content imagining the coach doing the imitation.
Some people think it sounds like Kermit the Frog meets the Macho Man. Judge for yourself below:
