1999 commercial for Pepsi featuring that cute little Pepsi girl Hallie Kate Eisenberg.

When patronizing a local soda fountain, she is informed she can't get a Pepsi, instead she must have a Coke. She then goes all Joe Pesci on the server (Pesci's actual voice is dubbed over) explaining calmly and cooly that she will have a Pepsi or things won't go well.

Hallie's Pepsi commercials were very popular. Previous commercials had put the voice of the Godfather (Marlin Brando) into her mouth.

Hallie graduated from high school in 2010. Does that make you feel old?

This 1999 commercial aired during the season premiere of The Simpsons.
