User blog comment:Kuzlalala/Lala's Long but Orderly Put Theory about Phineas and Candace's Biological Father/@comment-3298984-20110809050702

Pretty good theory! But, with the new movie, timing is an issue now. The Flynn-Fletchers obviously adopted Perry when the boys were toddlers, five maybe. Now, you may say that Perry was the father, turned into a platypus, and then was adopted out, but I'm not quite sure. It seems to me that the OWCA either picks the pets up from anywhere in the world and trains them, ot they breed them themselves. I don't know. Cool theory, though. Although I am much more for the Heinz theory. Phineas and Doof look too much alike.
