On display in the museum was this model built entirely of toothpicks by someone who clearly had too much time on his hands. Anyway, ahead of me was a cute little girl of perhaps thirteen summers who looked at the model briefly then turned to a docent and asked, "Why didn't they use colored toothpicks?"
The gentleman had a look on his face which clearly indicated he had never before heard such a question, nor did he seem to have a ready response in his repertoire.
The placard indicated that the construction required 85,000 toothpicks.
Bigify for detail.
