Yes, this headline is as bizarre as it sounds.

Irish actor Jack Gleeson, more familiar to most as Joffrey from Game of Thrones, performed a four-hour long show today at The Kilkenny Cat Laughs Comedy Festival dressed as a cat, in front of an audience of cats.

Entitled Pangur Ban, Jack was reenacting the 9th century Irish absurdist poem written by a monk about his cat.

The performance went on for four hours today and passersby were able to watch through a window.
