Things you've only just noticed after years of viewing...
The mark of a classic show - you see something new even if you've seen the show 50+ times already. Throw your hats into the ring here with the things you only noticed when you recently watched AWP...

Before Barry's miscue/fluke when they're playing snooker in the Portland, I never realised Dennis wipes the chalk off the tip of Barry's cue.
