America's given The Simpsons a real stamp of approval to mark its 20th series - putting each of the famous family on their own 44 cent (31p) stamp.
It's the first time a television series has been featured on American stamps while the programme's still being shown on primetime TV.
Actress Yeardley Smith, who's the voice of Lisa in the show, said: "If this isn't the measure of iconic status in our culture, then I don't know what is."
The artwork for the stamps has been designed by Simpsons creator Matt Groening, even though he reckons he can't draw the characters well enough any more.
"Look, they're not right, but they've got personality," said creator Matt Groening. "And that's been the story of my life." They look pretty good to us Matt!
