Dude, you have a weak stomach if you can't handle brown mustard. Then again, how can you keep PB down? The stuff looks, smells and probably tastes like baby cack.
I just looked in my refrigerator and there's a nearly empty bottle of dijon mustard in there but going to the store for more mustard will just have to wait so if we want mustard on something we'll just have to use the yellow mustard which is still half full.
