Hey Dude was a show on Nickelodeon from 1989-1991. It was set at the fictional Bar None Dude Ranch in Arizona. It's focus was on the predicaments that the teens and the ranch owner, Mr. Ernst, got themselves into. It was a great show to watch growing up and is missed by many.
"It's a little wild and a little strange...
when you make your home out on the range.
So, start your horse and come along.
'Cause you can't get a ride if you can't hold on.
Singin' yippee kai aie ay. (Yippee kai aie what?)
Like the cowboys say. (Sing it again now.)
Yippee kai aie ay.
'Till the break of day.
(You'd better watch out for those man-eating jackrabbits... And that killer cacti!)
Hey Dude!"
