Unfortunately, anything that's NOT in the house! Which is what made a recent birthday such a good one. My girlfriend woke me up with a pipe freshly loaded with some of the best stuff we've ever had, let me wake-n-bake then took me to the best all you can eat buffet at a local casino so I could pig out! Once I got over the "everyone will know" paranoid fit... I ate everything I could get my hands on, we hit it at just the right time between breakfast and lunch... Had the best of both worlds, I MADE MY SELF SICK! And loved every minute of it.
