Am I the only one to notice that Jim spends a great deal of his time looking hilariously like a startled hen?

The way he sits bolt upright with his mouth partly open (especially when anyone doesn't agree 100% with the Gospel According To Jim) is the spitting image of a chicken that's just had a fright. It makes me fall about laughing every episode.

I always expect him to say 'Bcaaak!' at those moments and wonder how many times the production crew have to wipe crushed egg off the chairs he's been sitting in...?

I think it's the slight turn of the neck as well that really sets it off.

I keep chickens in my garden and this made me fall on the floor laughing. That hit the nail on the head, he looks exactly like a startled chicken!!!! ROFL!

I totally see it, lol.

Me too. Well spotted OP. Chickin' Jim from now on.
