Liam Neeson hasnt been to confession since he was a teenager due to a row over masturbation.

The Northern Irish actor chronicled the incident in a clip released Friday for an upcoming episode of Conan OBriens podcast. In the video, he detailed how his honesty with a traveling missionary turned him off from confession forever.

I had learned how to pleasure myself at home, onto the sheets, Neeson began, saying hed also looked up the word for what it was called.

Masturbate? Masturbation? he continued, reenacting the moment. OK, that seems harmless enough. Ill say that.

During his confession, a 15-year-old Neeson cleverly began by discussing boring trivialities about arguments with his family before finally revealing that hed masturbated.

He said the missionary screamed so loudly that old women just outside the confessional began kneeling and saying their prayers. Neeson told OBrien that the mans booming voice allowed them to hear everything.

You what?! Neeson said, imitating the missionary.

This guy, literally, I mean, he almost said things like: The grass will grow over the palm of your hand before youre 21! Stop that evil practice! Neeson added. Hes shouting this! That was the last time I ever went.
