Definitely "bubbly in the fridge" was one people found hilarious, because it was so camp and OTT. It is a fabulous scene.
Gail and Eileen's legendary brawl on the Cobbles in 2004 produced some fantastic dialogue. I'm sure it wasn't meant to be a comedy scene, but the sight of Gail out in her dressing gown screaming like a fishwife at the Grimshaws door, was just brilliant.
Coupled with great lines Eileen had. "Go 'ome Gail!" "He will needs an aids test after sleeping with your slag of a daughter" "She's been dropping grandkids since she was 13" "She didn't need much persuading, she never does!" I mean they're really big insults but they're amazingly delivered.
The actual brawl itself is pantomime. Gail has some cracking lines too "Oh look, heres the other one. The rest of the village people" as Jason arrives on the scene in a hardhat.
Best catfight ever on Corrie I think.
