Dominic Monaghan outside the El Capitan Theatre in Hollywood for 'Jimmy Kimmel Live!'. Los Angeles, California - 29.04.09

The actor reveals his encounters with animals, sea creatures and reptiles were nothing compared to his muay thai lessons.

Monaghan admits he picked up the basics pretty quickly and started to think he could take on the champ.

He says, "I went to this thai boxing place for, like, a day and a half training... and in the middle of the session, the guy says to me, 'The 19-year-old champion of Thailand is here and he wants to meet you and train with you.'

"I swung a couple of kicks at him and I think I got a little too cocky... He grabbed my leg and just walked me to the corner of the ring and I knew at any given point he could have snapped my ankle, but instead he just dropped me on my face and kinda waggled his penis in front of me."
