I can't remember if I've posted this before.
But I ran across it again today, and it still makes me laugh.
Cool Unicorn, Bruv.
A short film.
(My favorite bits -- spoilers! -- include the line "Onna hill it is well fast!" and the very end, where the unicorn does, indeed, fart a rainbow from his horn. That cracks me up every time.)
