If you don't know what the "Mile-High" club is - stop reading this now and go HERE.
If you're still with me, then congrats on being an informed adult! Whether or not you agree with the idea of joining the MH club doesn't matter, and I'm not interested in hearing your personal stories of joining it either. In ANY capacity.
But our Seattle-boy Macklemore is definitely a part of the Mile High club!! He explained to TMZ exactly how, and the video is below. Watch at your own risk.
