the first perfect episode of season 3. i thought it was funny when dr. dof. is fighting the other perry the platypus and sandwiches were everywhere and they were on the levers and the other perry the playtpus kept eating those and the major m and carl didn't know that it was the other perry the platypus. that was just hillarious. the phineas/ferb plot was hillarious. i cracked up a lot in that plot. overall 10/10.
