Travis Kelce appeared to be just a wee bit drunk at the Chiefs' Super Bowl parade Wednesday ... slurring his way through a rendition of "Friends In Low Places" -- before Patrick Mahomes had to snatch the microphone away from him.
The hundreds of thousands of Kansas City supporters in attendance at Union Station couldn't wait for the tight end to hop on the mic at the championship celebration -- and, initially, it looked like he was going to deliver a speech for the ages.
THIS IS CHIEFS KINGDOM!
