Dude. We were all in his basement like a week ago. I just happen to know the promoter, she needed to fill the spot, called me, and we were all smash drunk when we said yes, okay? Please stop yelling at me?
There are plenty of sources of fat that don't involve real butter. Avocado is loaded with fat, for example. Please note that I am not a doctor and this isn't medical advice and I don't even like avocado.
