The guest was George.

Ill admit, I went home and changed immediately.

Though Clooney wasnt familiar with the long-running reality show (say it aint so!)

he enjoyed what he saw.

Grodner never told the HGs that Clooney, of all people, had toured the facility.

I have to say he was one of the nicest celebrities Ive ever met, she recalled.

He was really fascinated.

Walking around behind the scenes was something that was intriguing to him.

That was a big one.

That was a highlight.
