The celebrity chef, 55, was on the show to promote his new TV series Next Level Chef when host Fallon, 47, asked him to settle a series of food dilemmas.

But before he agreed, Ramsay’s toddler, who was getting ready to go to bed, made an on-screen appearance.

Ramsay put Oscar on his lap but the youngster turned shy and refused to wave at Fallon or say anything, forcing his famous chef dad to quip: ‘He wasn’t happy with his dinner!’

After Ramsay handed Oscar back to someone offscreen, he agreed to play the segment called Gordon Ramsay Settles It and critique Fallon’s sandwich making skills.

Ramsay said: ‘A sandwich should look edible, yours looks like a diaper,’ before telling the host to pick up two pieces of bread and put them on his ears. As Fallon did, the chef laughed and told him: ‘You’re an idiot sandwich!’
