These two surfers had to give an unexpected surfing lesson over the weekend - to a baby seal.
Matt Stanley and Andrew Flounders were surfing off the coast of Northumberland in England when this little guy popped up out of the water and climbed onto Matt's board. Their GoPro camera captured the seal pup's attempts to stay up on the surfboard to the delight of the two surfers.
Matt told the BBC that the pup had a hard time balancing.
Well ithis first time surfing.
Matt also described it as a once-in-a-lifetime experience.
"We had been in for about 45 minutes when the seal came along. I've seen them there before but they are usually far away. This one nudged Andrew's foot in the water and started getting curious," he said.
"It kept sliding off, but every time you caught a wave it would surf in on the white water."
