LOL: ghost pournelle sends this hilarious clip of Liam Neeson doing some "improv comedy" with Ricky Gervais
Suuuuuper funny, thanks!
Here's a fuller version thanks to Michael Puttre
The joke is that rather than going along with the improve -- doing the "Yes, and" thing, where you agree to whatever your partner has created and go along with it -- he keeps saying "no" to anything Gervais offers. It's a great sketch. It was also a great sketch when Gervais did it first on The Office.
