For a successful ad, you don’t need elaborate joke setups, star athletes flexing, or the latest Gaga hit pounding in the background. All you need is a simple British grandma, two boxes of tea, and a cheeky reveal at the end. That’s what discount grocer Aldi (a.k.a. the German owner of the hipster brand Trader Joe’s) shows in this 20-second commercial that has gone shockingly viral in the UK. Watch and be amused.
