Will Ferrell was ‘so embarrassed’ by his real name growing up

What's really in a name? 

During Tuesday's episode of Christina Applegate and Jamie-Lynn Sigler's "MeSsy" podcast, Will Ferrell opened up about an embarrassing childhood memory that haunts him to this day. 

"Who is 10-year-old Will?" Applegate asked.

After detailing his straight-to-curly hair transformation period, Ferrell said, "At an early age, I still liked to make my friends laugh."

HOLLYWOOD STARS WHO HAVE MADE HISTORY AND ONLY GO BY ONE NAME

However, the funny man admitted to feeling self-conscious about one thing in particular: his real name. 

"This is a minor thing in terms of – it's not really even trauma – but I remember feeling so embarrassed because my real name is John, John William Ferrell, so first day of school, I'd be John," he recalled. "The teacher would be like 'John Ferrell?' and it was so embarrassing to me to have to say 'Here, but I go by Will, I don't go by John.'"

Ferrell said it took his teachers quite a bit to catch on, a time period that was "excruciating" for the actor.

"I don't know why it was so embarrassing to me to have to explain, 'I'm actually Will,'" he added. "People are probably going to be listening to this going, 'This is the lamest thing ever.'"

"We just lost anyone named John," Applegate joked. 

Ferrell isn't the only actor who famously dropped or changed their first name. 

Earlier this year, Emma Stone revealed she'd actually prefer to be called by her legal name. 

"It’s just because my name was taken [by another actress in SAG]," Stone, who was born Emily Stone, told The Hollywood Reporter in a recent story. 

The actress admitted that people she works with will call her Emily after she "gets to know them." 

"Then I freaked out a couple of years ago. For some reason, I was like, ‘I can’t do it anymore. Just call me Emily.’ Nathan [her co-star in 'The Curse'] calls me Em, which is easier," she told the outlet. 

She also explained that she prefers to be referred to as Emily by fans, stating, "That would be so nice. I would like to be Emily."
