Aside from the fact that it's scorching outside, here's just another reason to steer clear of those embarrassing Christmas jumpers this festive season.
A primary school has been forced to apologise for accidentally including a picture of bonking reindeer on its newsletter.
Hyde Park Junior School sent the letter to pupils and parents urging kids to take part in Christmas jumper day for charity.
But it became Christmas humper day when they decided to use an image of a jumper with a saucy festive pattern - four randy reindeer doing the dirty.
The 360-pupil school in Plymouth, UK, has now removed the newsletter from its website that went up on Monday.

The school's principal Tina Jackson admitted the blunder happened because they 'didn't look closely enough' at the image.
"Unfortunately we didn't look closely enough at the picture we used to show our support for Save the Children's Christmas Jumper Friday," she said.
"We're sorry if it has offended anyone and hope it doesn't spoil our good intention of encouraging pupils to support a very worthy cause."
Although parents were shocked by the mistake, some also had a good laugh.
"I'm a bit shocked that a primary school have sent out a newsletter with an inappropriate picture... Something to make you laugh?" one parent said.
