It’s still kinda wild how Phineas and Ferb managed to completely hijack an idiom. Now whenever someone hears a sentence leading with “If I had a nickel for everytime […]”, odds are their brain auto fills with “I’d have two nickels. Which isn’t a lot, but it’s weird that it happened twice,” rather than “I’d be rich,” or “I could [action that requires purchasing something requiring an obscene amount of money]”. Y'know, what the idiom originally was
the thing is, the phineas and ferb version is just so much funnier and more actually applicable
original idiom is “anything that happens a lot”
p&f version is “weirdly specific thing that happens more times than would really make sense”
