This is a variation on an old joke by Bill Cosby. His version is that he and his brother thought their names were Goddammit and Jeezuzchrist as that is what their father always yelled at them. One day, their dad yelled at Bill, Goddammit, Stop that! Bill replied, "But Dad, I'm Jeezuzchrist!"

Dog version: Hi! My name is NO NO BAD DOG, what's yours?
Cat version: Hi! My name is GET OFF THE COUNTER, what's yours?

My horse name would be Wide Load.

I tried to draw the wild horses more realistically which is why they were done in colored pencil. Since Whoa Dammit is telling the joke, he's done in my cartoon style and in marker.

colored pencil, marker and ink.
