Here's why you might wanna tell somebody if you're going to attempt to cross the choppy waters of the English Channel in an inflatable kayak:

This dude was out there in the middle of the channel for 48 hours!

In his swim trunks!

A British kayaker wearing only swimming trunks has been found clinging to a buoy in the middle of the English Channel after his inflatable kayak capsized.

The man, who was wearing only swimming trunks, claims to have set out from Dover heading for France.

He was found by a Dutch fishing crew, clinging to a buoy halfway between England and France, where he had apparently been for about 48 hours…

According to a Facebook post by de Boer [the boat's captain], the man had severe hypothermia - his temperature was 26C - dehydration and was covered in bruises. He said that it was a miracle he was alive.

Dude's body temp when they found him was only 78 degrees!

Absolutely crazy that this guy is still alive!

Even a few more minutes in that water could've been the end of him.

And you gotta give it up for the treatment he received from the fishing crew who found him:

Mr De Boer noticed him "waving like a madman" after a "disappointing" morning's fishing.

The crew immediately threw the man a lifebuoy and hauled him aboard…

Once he was on board they wrapped him in blankets and gave him a Snickers bar.

Nothing like a good old Snickers bar to bring a guy back to life!

The unnamed man was quickly transported to a hospital in France via helicopter, and is — I just have to say it one last time — very lucky to be alive.

Rock on, sir.

Rock on.
