My Favorite Quote of all time
"You put on your boots, click into
your bindings, dust the snow off your skis,
and head out for the chairlift. It doesn't matter
that you failed your last test, didn't get the girl,
or that your life is on a one way trip down the shitter.
Your world is right for the next couple of hours."
but if you say it right with emphasis on the fu and du while just trailing off the ck/s it does. kinda like all rap stars and how they only rhyme the first syllable making two completely different words rhyme
