On Monday night's episode of "Jimmy Kimmel Live," one lucky Liam Neeson "fan" (i.e., a member of Jimmy Kimmel's staff) got the chance to live out his ultimate fantasy.

So what was that fantasy, you ask? To get an autograph from Neeson, or a photograph with the actor? Or maybe just shake his hand, perhaps?

Nay. In his own words, this "audience member" asked Neeson to "scare the s***" out of him, right then and there. And Neeson — well-known for his imposing presense in films such as "Taken" and the upcoming "Non-Stop" — was more than happy to oblige.

As the house lights came down and a spotlight shone on Neeson's face, the 61-year-old actor stared straight into the camera while reciting a sinister speech along the lines of his monologue in "Taken."

"I want you to listen very carefully, Matthew," began Neeson. "Before this night is over, I will kill you. But before I kill you, I will make you suffer pain so unimaginable, you will wiggle, and beg, and pray for the gift of death."

The actor continued his threat as ominous music began to swell behind him, telling "Matthew" that he won't even find peace when he "wake[s] up in hell."
