well I never thought of ranking the coolest nerds, but yeah, after me, John Denver is the coolest nerd ever.

He unashamedly used cannabis
He was on the muppet show
Loved his state and made an effort on environmental issues
yeah, a lot of his songs were way sicky sweet, but he had a nice voice and I love some of his songs. I mean, hellloooo, Grandma's Feather Bed anybody?
