We've seen some fun wind-up toys in our time, but these old biddies really take the cake...and the cup of watered down coffee with a slice of pumpkin praline pie. Ooh yes, m'dearies, Racing Grannies are charming old ladies that are set to take the world of wind-up racing by storm.

Sold in pairs, each Racing Granny is equipped with a sleek walker, slippers and shopping basket. Simply wind 'em up, line 'em up and adjust their arms into 'race mode'. Then watch as your puttering old dearies hobble along as fast as their little legs can carry them.

Racing Grannies make great desktop companions and their handy little baskets are perfect for storing paper clips, pins and spare buttons from the collection you keep in the kitchen drawer. You can even use them to deliver things across the desk to colleagues. We've taken to sending candy. And not just any old treat but the horrible decades-old wedding mints that seniors seem to love.

Why not organize your very own office 'Gran' Prix and give your Racing Grannies suitably speedy names while you're at it? Here at the Firebox Retirement Lodge, Gertrude Schumacher and Betty Barrichello have just competed in a real nailbiter. First over the line won a tin of fruitcake, a photo of Estelle Getty and a thorough hair bleaching. Viva!

We honestly can't overemphasize just how hilarious Racing Grannies are - the second you see them in action you'll crack up. Best of all they're fun for all ages. Even elderly (and not so elderly) relatives will love them. Indeed Granny Firebox nearly fell off her Rascal when she saw them in action. So hurry up and hit Add to Cart. We reckon Racing Grannies are going to shuffle off the shelves faster than you can say 'I've juff fwallowed my falfe teef.'
