Funny man and host Jimmy Fallon is never short of ways to put his guests in funny challenges.
In a recent episode of The Jimmy Fallon Show, he took on Maroon 5's frontman, Adam Levine, in a round of "singing" musical chairs.
Called the "Wheel of Musical Impressions", both men had to press on a button to generate a musician and a song title.
Things got funky when the generator churned out hilariously mix-matched pairings.
Jimmy had to sing the lyrics to "Old MacDonald Had a Farm" to the tune of Iggy Azalea's summer hit "Fancy", complete with animal sounds.
Meanwhile, Adam Levine impressed the audiences with Michael Jackson's "Smooth Criminal" paired up with the lyrics to popular children's show Sesame Street.
Who sang it better? See the video below and decide for yourself.
