What did I go and see yesterday? Is this Glasgow? Are you my sister? Have I had my pills?

Perhaps Alzheimer’s is setting in already because I know from the damp patch in my pants I laughed a lot yesterday afternoon, but can’t fully recall what at.

Three Australian actresses portray elderly ladies in the ‘Jurassic Park’ retirement home in Melbourne. The slight joke gives a clue to what’s to come: lots of obvious gags about incontinence, failing eyesight, forgotten sex, deafness and hip replacements … and it’s true some of the jokes are as whiskered as the residents and the dialogue needs the over-repeated “dear” plucking from it like white hairs on the old girls’ chins, but an almost sell-out crowd rocked with laughter. Sharpened up with a bit more topicality, this could become a regular Fringe favourite.

There are some hilarious moments, the best of which is the sex education balloon routine. A sketch about grandma giving her granddaughter a Mickey Mouse watch is both funny and touching, but the best gag of the afternoon comes in the ballroom dancing class and you’ll certainly remember that.
