If you think that you are the ultimate Zac Efron fan you might want to think again. While making an appearance with his "That Awkward Moment" costar Miles Teller on the Conan show the actor shares the craziest gift he ever received from a fan.

According to Us Weekly, the "Neighbors actor received a piece of skin from a fan as a gift. While talking to the host on Tuesday, February 4th the actor revealed his gross experience.

Conan O'Brien asked, "How strange does it get? You hear stories that women try to mail themselves to you."

Teller chimed in and said, "That sounds sexy and nice," adding, "[But] the story he told me was not in that tone."

The 26-year-old explained, "I was like, 'Zac, what's the craziest thing a fan has sent you?'"

Teller continued, "He was like, 'Oh, I had a fan send me a piece of their skin.'"

O'Brien replied, "What?"

Zac Efron, 26, then exclaimed, "Dude, imagine when I got it!"

The Disney alumni continued, "It's hilarious because you don't know how to handle it. You'll never get around it. I love all my fans."

O'Brien then joked, "You took it to the lab to grow a woman! It's such a strange thing."

Miles Teller quickly decided it was time to share another story about just how dedicated the "Parkland" actor's fans are.

He told Conan O'Brien, "Even as grown women -- we were doing this thing at Facebook and one of these women stood up and said, 'Hey Zac, I'm 27.'"

Teller continued, "I just had a birthday party and all my plates were from High School Musical. My napkins were High School Musical and my husband said it would be okay if I hugged you. Can I hug you?'"
