Sunday Brunch’s Simon Rimmer slices his thumb open live on air after making fun of guest Joe Sugg fainting over blood

SUNDAY Brunch's Simon Rimmer sliced his thumb open live on air, moments after making fun of guest Joe Sugg for fainting over blood.

The presenter had to plaster himself up after grating his thumb during today's show on Channel 4.

His kitchen mishap came after playing out a clip of Strictly star Joe collapsing on Great British Bake Off.

Last year the 29-year-old fainted into the arms of a paramedic after slicing his finger making a tray bake.

He went on to get a 'Hollywood handshake' and win the celebrity special.

But the Channel 4 presenter Simon and his co-host Tim Lovejoy found the medical emergency hilarious.

After laughing at Joe as he joined them as a guest on today's show, Simon later admitted: "Joe, I don't want to alarm you.

"But I've actually just managed to grate my thumb. If we have got the stand by team for when I faint..."

As he was halfway through making a dish, Simon said: "What I'm going to do is use spoons for everything now."

Joe put his head in his hands and shouted: "I'm a bad omen."

Simon was then seen searching for plasters before dishing up the plate of food.
