Whatever this man was taking, I want some. Helmut thinks his paintings will be valuable one day. I’m not so sure. But his boundless optimism and general spaciness will go down in history. Bob Ross (October 29, 1942 – July 4, 1995) was absolutely priceless.
He repeatedly stated on the show his belief that everyone had inherent artistic talent and could become an accomplished artist given time, practice, and encouragement, and to this end was often fond of saying, “We don’t make mistakes, we just have happy little accidents.” (From Wikipedia)

How to sound like Bob Ross:
Let’s just do a happy little painting
happy little strokes
just sort of let it happen
see how easy it is
I’m just an absolute fanatic for water -… love it!
That makes it sort of pretty
thought today we’d put in some happy little clouds
take out all of your frustrations and hostilities
Decide where your big ole clouds are going to live
clouds are very, very free
it doesn’t matter
happy little bushes
don’t want this little tree to be left out
all kinds of happy little things
Isn’t that super?
And it works so well
the squirrel hilton
We don’t make mistakes, we just have happy accidents
There it comes…
Whatever, just sort of scrub it in
