If you can't take the heat, stay out of the kitchen is the motto on both FOX's "Hell's Kitchen" and Bravo's "Top Chef." ET is with the two dynamic executive chefs and best-selling cookbook authors who run their respective shows -- "Hell's Kitchen" chef GORDON RAMSAY and "Top Chef"'s TOM COLICCHIO.

Each of the two hit series has raised the bar with each passing season, but that doesn't mean that there isn't drama in the kitchen.

"It is full on. It's boisterous. It's tempestuous," declares Ramsay, who is famous for his short temper. "No one has told me yet to slow down. I don't like cursing. That is the weird thing about it. Unfortunately, it is the donkeys that I work with that provoke me. But we do have good days. We do have good days when we run to perfection."

"The use of profanity this year is over and above where it needs to be," Colicchio says of the swearing on "Top Chef." "But it is a reality show and no one is prompting them [the contestants] to talk like this. This group of individuals, whether they don't have the vocabulary to use other adjectives, I don't know ... I'm surprised when they're surprised that they're portrayed that way. It shows a lack of maturity."
