For my bridal shower....this was a game we played. My mom broke everyone into teams...I was told to leave the room (had not a clue WTF?)..each of the 3 teams had a "model". The only supplies given were rolls of TP and tape.
When I came back, I had to judge. I laughed so hard! None of them were as good as the pictures in the link though...
Here is a picture of the "worst" one at my shower. Lol.
