“How do I know this you ask? I’m in a bowling league with Starman.
He told me over a couple of beers. At least he claimed to be Starman. Lent him some money. Haven’t seen him since, but I’m pretty sure it was him despite the huge height, weight and age differences in their looks. So… probably shouldn’t have given him my credit card. Anyway, that’s how I know.”
