This is the best way to do it because they will go further on the off chance that you are a prime scamming victim rather than someone winding them up. Hooked one for about 25 minutes once because I said the phone wasn’t next to the pc, so I had to keep shuffling between the two. Every time I came back from the pc, I gave the phone a whack on the table to make them jump.
I don’t want it to collapse. Just stop being an arsehole.
