Beatles legend Paul McCartney persuaded makers of popular animated sitcom "The Simpsons" to make one of its characters Lisa a vegetarian in exchange for a guest spot.
The Huffington Post reported that the makers of "The Simpsons" agreed to make Lisa, the family's iconic daughter, a vegetarian in exchange for the former Beatle's agreement to play himself on a 1995 episode called - - Lisa The Vegetarian.
Actor Hank Azaria, who has voiced several characters over the course of the show's 27 - series run, told the blog: "I can tell you, over the years, they were tempted a bunch of times to have Lisa break her vegetarian vow. "
He added that they "probably have not because they made that vow to Paul.
No, you don't break a knight's vow.
As we've learned from 'Game Of Thrones', you do that at your own risk. "
"The Birdcage" actor features in the episode alongside the rock legend, playing Apu, an Indian immigrant character who was a fixture on the programme.
"The Simpsons" currently airs in India on Star World and Star World HD.
