Super short trip to Mr G's and when I arrived I realized I'd visited him several years ago! Mr G remembered the previous mission in detail. I swapped over the phones and helped Mr G familiarize himself with the new phone's keypad. Mr G told many jokes whilst I was installing the phone (one included in the title) and told me a scientific themed one as I left. "What's Prusiner's favourite flavour crisps?", "prion cocktail". 😬
