It was a fish that would start to smell once the car heater went on. I recently watched those two Grumpy Old Men movies again on TV and couldn't stop laughing.
We will never see another pair like Jack and Walter again - what a team they were. Burgess Meredith as Jack's father was hilarious in those scenes with the actress who played Sophia Loren's Italian mother.
Both Ann-Margret and Sophia Loren were wonderful in those two priceless films.
