Recently widowed old woman who lives next door to mum and dad asks me to look at something in her garage (she's selling house so packing stuff up). Once in, she opens a drawer and asks what I think "this is". "Hmmm...." I say, "looks like a grenade to me. Yup. Your husband worked in South Africa a lot didn't he? Are all these guns his too? Yeah, you might want to call someone, Mrs"
