Snow on the roof, furnace in the basement!
At the nursing home, old widower Harold and old widow Mavis had a little relationship going. On movie nights after the lights went down and the film started rolling, Harold would unzip his trousers and Mavis would give him a little fondle. Then Harold started avoiding Mavis and Mavis heard through the nursing home grapevine that Harold had started seeing another lady. Mavis confronted Harold and demanded to know, "What does she have that I don't have?!" Harold replied, "Parkinson's."
