If you ever feel chilly doing PE in winter, spare a thought for these football players in Finland who play on a snow covered pitch!
The players are part of FC Santa Claus - a real football team where the players dress as elves.
The club was formed in 1992 and has floodlights and underground heating to help players beat the frost.
Off the pitch, some of the players even help out at the post office that receives letters to Santa.
"I come here to read the letters from the kids all over the world," said Jukka Markkanen.
"That's something nice to do once in a while when not playing football."
