You never know what's going to happen on live television.

Sometimes, it can be a misspoken word coming out as a curse, it can be someone making an off-colour joke that gives everyone a fit of the giggles, or in Donal Skehan's case, he slices off the top of his finger with a very sharp knife.

That's pretty much what happened earlier this morning on Saturday Kitchen when, in the middle of slicing up some herbs, he sliced through his forefinger and the whole thing was caught on camera.

Better still, Skehan tried to keep chopping and was only stopped when blood fell out onto the chopping board. Take a look.

To his credit, Skehan stopped and threw a tea-towel around his finger and then later applied a plaster, which he then duly shared a picture of on Twitter.

TAKE OFF THE PLASTER, LET'S SEE THE GROSS CUT.
