User blog comment:Kuzlalala/Why am I So Curious about Phineas and Ferb's Missing Parents/@comment-2133790-20100626055750

xD oh god this is hilarious. Doofenshmirtz can't be the father because the triangle head are different...and he had an ex-wife with a daughter, Vanessa, who is only a year older than Candace. Since Candace is actually Phineas' sister that would mean Linda and Doofenshmirtz had to stay together for a while to have Phineas... And Perry? Ok...wierd...because they showed Perry as a baby before with a baby Phineas :P

For Ferb his grandfather MAY have the green hair. (You never know since all his pictures and flashbacks were black and white) Also....it's a cartoon for pete's sake >.<

I hope they at least mention their parents in the movie though. Just to satisfy my curiousity, just a little sentence or two is all I ask...
