If you haven’t called your dad to wish him a Happy Father’s Day yet, we’ve compiled a list of celebrity horror stories to motivate you off the couch and onto the phone to tell your pop how much you love him.

When Angelina Jolie won a Golden Globe for her performance in 1999’s “Girl, Interrupted,” instead of a big congratulatory hug from her famous father, Jon Voight, and her mother, French actress Marceline Bertrand, she got the silent treatment for two days!

The mother of three’s brother, actor James Haven, attributed their parents’ silence to a “weird sort of competitiveness.”

“Buffy the Vampire Slayer” star Sarah Michelle Gellar told the London Telegraph that her father “is nonexistent in my life and I have nothing to say about him.” The actress’ father left her and her family when she was a small child and has not spoken to him since she was 11 years old.

Because of his father’s drinking binges, Chuck Norris insists “to this day, the mere smell of booze makes me feel ill,” reports London’s Daily Mail.

The “Walker, Texas Ranger” star’s father was “a terror” when he was drunk, according to Norris, and even though he died 26 years ago, Norris remains a strict teetotaller.

“American Idol” star Clay Aiken can relate to Norris’ childhood plight because the singer’s biological father hit the bottle pretty hard as well. Aiken told Rolling Stone that his pop’s drunken rages became so violent he and his family fled to escape him!

“We moved so he wouldn’t know where I was,” he said, adding that his mother’s second husband, Ray Parker, was “the only dad I ever had.”

To add insult to injury, now that Aiken has risen to stardom, his abusive dad has been reaching out to get in touch with him. But the “Idol” says he won’t be sucessful in his efforts because “I don’t want to give him the time of day.”

Maybe these bad dads should take the advice of Tommy Chong, of “Cheech and Chong” fame, and learn to relax with their kids.

The comedian admitted to the Honolulu Advertiser that he still fires up the wacky weed a few times a week and proudly added that he “turned on” his 21-year-old son to the drug that made his act famous.

Chong said he presented his son with a “you’re-a-man-now bar mitzvah joint,” and the two have been “tight” ever since.
