Chris Packham left viewers feeling a little squeamish when he got up close and personal with grass snakes on Springwatch - even letting one lick his eye.
The wildlife presenter visited Norfolk to hunt for the slithery creatures.
And when he found them he was quick to pick them up, letting them writhe around his hands while he sniffed at them, declaring: "The smell!"
He even let one of the snakes lick his eye.
Fans on social media were impressed.
Some viewers apparently felt a little less comfortable.
