I Was a Middle Aged Robot

Candace is determined to win this year's father-daughter obstacle course but unfortunately, Lawrence finds Agent P's lair and his memory is accidentally erased by a memory-eraser gadget. Luckily, Carl had already made Flynn-Fletcher Family Robots for emergency situations. So Agent P operates a Lawrence robot to fill in during the race as Phineas and Ferb provide commentary from their broadcast blimp. Meanwhile, Dr. Heinz Doofenshmirtz invents "eulg," a solution that works the opposite of glue and takes everything apart.
