As I walk through the valley of the indian youtube channels
I take a look at my institute and realize it's worthless
But I've been teachin' and coachin' so long that
Even sharma ji thinks that I am the best
But I ain't never crossed a student that didn't deserve it
Me be treated like a genius, you know that's unheard of
You better watch how you learning' and where you writing'
Or you and your notebooks might be lined in chalk
I really hate to teach, but I gotta do
As they "learn", I see myself in the oi oi tee smoke
