Jimmy Fallon never disappoints when he has an idea for something a bit unusual with celebrities.
This one involves Maroon 5 busking on the New York subway and is absolutely brilliant!
We see loads of New Yorkers making their way home, when a band of 3 guys wearing beards and hats start performing.
The small crowd that start to gather don't know it's actually Maroon 5 and Jimmy in disguise.
They do "Crazy Little Thing Called Love" by Queen and the crowd seem to be enjoying it.
They then take off the disguise and reveal themselves, before performing the band's own track "Sugar".
