Jamie Oliver - Raunchy Chef?

Now I know some people seem to think that I have a dirty mind...
But i'm interested to know if it's me or whether Jamie Oliver in his new show 'Jamie at home' is taking the piss.

In a 3 min segment about 'Mushrooms' i caught these words and sayings:
"Bare end"
"Knob"
"Drips"
"Toss"
"Taste the cream"

This was later followed up with the phrases:

"It's coming"
"look at the juice coming out"

Naughty Jamie!
