It’s not funny to imitate an old man walking and even less funny when it’s done by a police officer trying to impress some onlookers at the old man’s expense. It is perfectly appropriate to cheer for the old man when he demonstrates the proper use of a walking cane. The unknowing onlookers had mixed reactions on the use of the cane but that’s ok as this was all Just For Laughs and no old people or policemen were harmed.
