Best misheard line I've ever personally overheard was one half of a phone conversation while I was standing in the line at the store:
"No no no... the Greeks left behind a wooden HORSE, not wooden whores! Neeeeigh! Clipclop! Horse!"
As I previously posted in another thread:
I think this might be the most confusing conversation I've ever had. Picture a 5 minute conversation between two people, talking about movies, where we're both think we're talking about the same movie, but we're actually talking about two completely different movies.
The movies in question: "51st State" (known as "Formula 51" in America, I believe) and "50 First Dates" (say them out loud and if you're not concentrating, it's very hard to hear the difference).
I was talking about the former (a British crime comedy in a similar vein as the Guy Ritchie Lock Stock movies, involving drugs, guns, and extreme violence), while coworker was talking about the second (an American romcom starring Adam Sandler and Drew Barrymore, about a woman who suffers from amnesia who has to be wooed anew every day).
Conversation snippets include:
Her: "I just thought is was so sweet in places"
Me: "Really?!" (thinking about the bit where the corrupt cops drop a cargo shipping container on a suspect by mistake)
Her: "I loved it when the main girl made a house out of waffles!"
Me: "Uhhh... I don't remember that being a plot point. I just remember her shooting her exboyfriend in the behind. But Samuel L Jackson playing golf in the nude was hysterical"
Her: "Shooting..what? Wait... Jackson? He was in it? NAKED?"
Me: "Ummm, yeah, he's the chemist who makes up the magical drug formula. You know, the same guy who mixes up the chemicals that make the bad guy explode all over the room."
Her: "Magical drug? What? Exploding dude?! WHAT?! I don't remember that".
