At a former workplace one of the ladies turned 40 so all the other employees got her a black cake with a big 40 on it. The frosting and cake were BLACK and we all started eating the cake. After a short time someone smiled and we all realized the cake was turning our teeth and gums black. We all got a big laugh and the more we laughed and smiled the funnier it was.
The next morning we discussed the surprise color of the morning constitutional. Black!
