Shaun of the dead has so many jokes in that its hard to catch them all. There is some good YouTube videos that also explain them in case you missed any.
I remember showing my late dad Hot Fuzz. He was laughing so hard and practically wheezing at how relatable it was, from a US law enforcement background lol. (Especially when he's fielding outrageous questions at the primary school LOL)
That was a really good time spent with my dad. I love that movie. We'd be quoting it all the time hahaha.
"Aww man did ya say anythin cool?"
"I uh, smashed him over the head with a pot and said 'playtime's over'."
