Did you go #1 or #2?

Was in training for a couple days last week in a newer building on campus. They have these awesome efficient/water-conserving toilets where you flush it one of two ways depending on whether you went #1 or #2. It was so funny, I had to take my phone in there to snap a picture of the instructions on the back of the stall door. Oh, and for those who are curious (I certainly was) -- it sounds the exact same when you flush, no matter which way you "push" the lever. Yes, I did a little test ;o)
