It's a lesson late night host Jimmy Kimmel learned the hard way, after getting Gordon Ramsay to taste test some Girl Scout Cookies.

"I'm gonna first of all warn you this is almost like sacred territory you're entering," Kimmel said. "There's the American flag, and there's Willie Nelson and then we have Girl Scout cookies. Those are the three things we care about."

After being shown the cookies on offer, Ramsay scoffed: "Visually they look like dog biscuits".

The chef managed to swallow the first cookie without much effort.

"Yeah, that one is OK," he said, nibbling away at a small bite.

One of Kimmel's staff then brought out a glass of milk for Ramsay to help him enjoy the next one, an unusual coconut creation.

Upon tasting the cookie Ramsay remarked it "tastes a bit weird" before screwing-up his face and spitting it out.

But it was Kimmel's favourite, 'Thin Mints' that really left Ramsay with a bad taste in his mouth.

"That is like a cheap after eight dinner mint," he said before again spitting it out.

Doggy bag to go, perhaps?
