Toadpipe: i'm not sure which hole that guy is sticking it in. side ass? but then again, i never had the "wang piece" in my lego sets
evidently legolanders are blessed with two anal orifices. and those studs all over the bricks and base plates? butt plugs. who knew?
but seriously, the coolest lego stuff i've ever seen are a few escher reproductions that some enthusiasts made. there used to be a website explaining how they did it but i can't find it. here are some pics i googled up though
