Phineas and Ferb
Triangulation
[ Verse 1 ]
Roger Doofenshmirtz, we know, is six feet and two inches tall
And the beam that hit him left a weird impression on that wall
So I took the angle from that point of where I knew he stood
And I found the building just like that because I understood

[ Chorus ]
(Triangulation!)
That's how I figured it out
(Triangulation!)
Now I'm left with no doubt
The only geometric process using data I possess...
That could pinpoint the conclusion of my scientific quest
Triangulation!
