Colin Farrell's childhood crush story is hilariously strange

Many young boys and girls have posters of a celebrity crush up on their bedroom walls.

It's pretty normal, right?

Leaving notes and candy in the hope your crush -- who also happens to have been dead for 40 years -- will come and collect it, though -- that's slightly less normal.

In the clip above from Jimmy Kimmel Live, Colin Farrell tells the story of the crush he had on Marilyn Monroe when he was younger.

Okay, so he may have left her Smarties and then got offended when she didn't visit him, but cut him a bit of slack -- he was only 7 or 8 at the time, after all.
