We have very little doubt that when the creators of 'The Simpsons' designed the character of school bus driver and part-time rock star Otto, they based it directly off one of the most famous rock and roll musicians of all time. Slash is one of the very best guitarists who ever lived, writing the riffs which made Guns n' Roses such a huge deal in the 1980s. Every time you hear 'Sweet Child of Mine,' you're listening to Slash at his fret-melting best. Slash quit the band in the 1990s, but has since returned to the fold, and the legends are back on tour again.
The only difference between Otto and Slash is that the 'Simpsons' character never made it as a rock star, and doesn't appear to have a top hat anywhere in his wardrobe. He's not afraid to pick up a guitar and play, though, and when he does, he seems to be quite adept at it. Given that Slash is now well into his 50s, maybe it's not too late for Otto to make it as a musician after all.
