PBL Tshirt

I was supposed to design a tshirt for my PBL club. I asked for suggestions and no one gave me any. So originally I was just going to put "PBL" on the tshirt. But then I had visions of various typographic styles for the letters "PBL" including the one shown below, a cheesy play on the old phrase, "What time is it?" PBL time baby.
