Eichner was even featured doing his famous schtick at the Emmys this year.
But now it appears Burger King is trying to get in on Eichner's act.
In a new commercial, an actor who looks like Eichner but isn't as funny yells at kids on the street about BK's new chicken nuggets. Watch below:
After seeing the new ad, Eichner tweeted:
Hey @BurgerKing-thanks for stealing my act for ur new commercial!! Except its not as funny & everyone knows u stole it. GET YOUR OWN IDEAS.

Eichner's celebrity and comedian friends were quick to come to his defense:
Yo @BurgerKing, stop stealing from the hilarious @billyeichner and stick to what you're good at: giving me diarrhea.

Hey @burgerking, you were stupid if you think hiring some random actor to rip off @billyeichner was going to work. I WAS AVAILABLE!!!

Dear @burgerking, if @billyeichner stalked ppl in the street in a giant weird plastic head & royal robes selling his meat,YOU'd be SO PISSED

Eichner was moved by the suport:
I will put all this anger into the next season of #BillyOntheStreet! Thanks for all the incredible tweets. I HAVE THE BEST FANS EVER!!!

The truth is the only burgers I've ever liked are BOB'S BURGERS. Thank you and good night.

Then even McDonald's chimed in!
@billyeichner Can't wait to see you! Oh, and bring Elena!
- McDonald's (@McDonalds) October 13, 2014
And as Madonna once said, "Often imitated, Never duplicated." Love you all. Elena and I are about to enjoy some McNuggets.

Watch a recent "Billy on the Street" webisode with Amy Poehler below. Do you think Burger King copied the comedian?
