I had to sing this song in Kindergarten while dressed as Abraham Lincoln.

I think I did better but I have no video to prove it.

That kid is being played by Patton Oswalt in a Tim & Eric sketch, and he's on the Between Two Ferns set, and the ferns are being played by trees.

*sweeping hand motion* Across the plains of Texas...

at .17 it sounds like he's singing "and I won't forget the bling vagine and gaydar right to me."
