I cannot stand watching tv when someone is sitting eating, and we have to listen to them chomping on their cornflakes or whatever, while someone else competes to deliver their line over it. Worse than that, when they take a huge spoonful then deliver one of their lines through it.
Another thing that really makes my skin crawl is people having a snog on tv. It always seems to be the same sort of repeating kiss, each one accompanied by an odd, unnatural clicking sound. Revolting.
Ban eating and kissing from tv PLEASE!
