Monogram Rap This Old Man Phineas and Ferb

[Verse]
Agent P, over here
Let us get this thing in gear
There's a big old lump of trouble in town
Awful things are going down
Please go stop Doofenshmirtz
I know this puppet show's the worst
But I never said that I could write a song

[Outro]
Could you just leave? This is really embarrassing
