I think one of my favorite aspects of Phineas and Ferb is that the entire cast is a perfect example of the One Degree of Separation trope.
By it's very nature, I literally can't state how many connections each character has to each other or I'd be here all day, but it's wild.
I will talk about my favorite little example of it, though. So, Stacy knows Perry's secret identity thanks to a technicality stopping her from getting mind wiped after seeing him in action. That on it's own is funny, but she's also friends with Candace (Perry's owner who he needs to hide his identity from) and Vanessa (who also knows his identity as he fights her dad), which is hilarious. In this trio of teen girls only Candace doesn't know that her pet is a secret agent.
Here's a list of "one-degree" character relationships (mostly Perry specific ones) that I personally find hysterical:
1. Jeremy and Perry - Jeremy has given to guitar lessons to both his BOSS and also his NEMESIS.
2. Buford and Perry - Buford worked for his nemesis why is his life like this
3. Candace and Perry - see above (it's so stupid it's so fucking FUNNY poor Perry) (also Candace specifically has interacted with Doof multiple times like. Directly)
4. Linda and Doof - Linda and Charlene are literally friends. Like they go out and do stuff as friends. Take classes together. Not only is Linda one person away from running into her ex, she's one person away from her pet platypus
In conclusion: Perry is CONSTANTLY at risk of being discovered because his family and their friends are just too fucking friendly with his nemesis' family
