First it was Elmo now it's Charlie Brown.

Good Grief!​

The man who was the voice of Charlie Brown in the first "Peanuts" television specials has pleaded guilty to threatening and stalking both his ex-girlfriend and a plastic surgeon who gave her a breast enhancement he paid for.

City News Service says 56-year-old Peter Robbins entered the plea Wednesday in a San Diego court and could get up to three years in prison at his sentencing next month.

Prosecutors say Robbins called his former girlfriend dozens of times a day and told her he would kill her and her son if she did not give back his dog and car.

Robbins provided the voice of the title character in 1965's "A Charlie Brown Christmas" and 1966's "It's the Great Pumpkin, Charlie Brown."
