just my opinion,.... ive been thinking about it alot latly

I've considered this once, too, so it's not totally that weird to consider it. Your reasons are good, too. But I just don't really see Hines as Phineas's dad; if he was, wouldn't Phineas have a 50% chance or so of having his accent? That, and the one time Doofensmirtz ever mentioned doing anything with Linda was having a date with her; never mind having two children or even having a divorce.

I'm glad I wasn't alone in this theory though, and if Doof was Phineas's dad, that'd be...interesting. XD And I completely respect your opinion.

ya, that could also be the case,...

Actually, your accent isn't completly from your parents. It changes with everyone around you. Depends where you live. His mum had an American one so, he grew up listening to her so therefore...yeah

it could explain some things, but dooof only metioned 1 ex-wife.but it is possible, and perry will have 90% chance of getting a heartattak if he herd this
