O.k. this just told to me. thought it was funny. grampa invited his grandson over for the day. When the grandson arrives for lunch they both sat down to eat. The grandson had noticed that the plate didn't seem clean and questioned his grandfather about the dirty plate. Grampa replies, "its as clean as cold water will get it, now go ahead and eat." Later that nite when dinner was ready, the grandson noticed some egg left on the edge of the dinner plate and once again, questioned his grandfather why there was egg on the plate. Grandfather says, "I told you before, its as clean as cold water will get it-now no more questions." O.k. says the grandson and they finish dinner. After visiting a little while, it was time for him to get back home. When the grandson went to leave the grandfathers dog wouldn't let the grandson leave. The grandson called his grandfather. Upon entering the grandfather called his dog "come here cold water, here boy", come cold water.
