Super-Sized Skinny Jeans?

My 20-year-old brother is living with me for the summer. He recently did some grocery shopping.

Doritos, Pepsi, Ramen Noodles, Cinnamon Toast Crunch... and there was milk of course. His bones are still growing. I could make some jokes, but the truth is that this is more grocery shopping than I've done in weeks. I hope this junk doesn't end up in my "trunk."
