I'm answering my own question cos I'm cool as ' and I love walkin :p
"As cool as the other side of the pillow."---Stuart Scott
When I was growing up it was -
Be Cool like Fonzie!
So I was going to post a You Tube video of Quentin Tarantino's "Pulp Fiction" but there are a LOT of swears in the short clip, I wish NOT to offend . . . But the Clip has someone else whom I think exudes "Coolness" and that is Samuel L Jackson. In the scene he is telling everyone to be "Cool like Fonzi" . . .
Beware the language if you want to watch -
Marlon Brando in : The Wild One ! He was totally cool in it.
Evel Knievel was cool as'!
That one man or woman that gets that education first.
Mark Paul as Zack Morris from Saved By The Bell.
Those older women who have sense of style all their own.
