i feel like i see posts like this so much and it's kind of weird bc this applies only to like. a very specific subset of people (ppl who are into phineas and ferb + aware of the "two nickels" thing being repostet a lot) which is like. a subset of people in a fairly specific age range (the right age to have watched phineas and ferb so like. idk 15 - 30 year olds probably being generous) AND are active on specific social media platforms to have seen this joke repeated a lot so it burrows into their memory bc most people who just casually watched phineas and ferb aren't that likely to remember this specific moment (i know i didn't without the meme). and idk this is not a big deal i just find it interesting how often people online will post about something that is extremely specific to them and the social circles they move in as if it's a really universal experience
