Answering the phone

Taliban Takes on Telemarketers (Taliban Telephone)

When Love assumes it's my mum calling, he answers the phone with either "Ali Baba's vegetables and used camels" or, like the turban dressed man in that flash animation, "Taliban".

Well, the other day it WASN'T my mum on the line. It was a telemarketer. And apparently the line went very, very silent after he picked up the phone and cheerfully said "Taaaliban".

I'm not sure if I should roll on the floor, laughing, or ban him from ever answering the phone again.
And no, we don't have caller ID. We should, because our phone can show it and it's supposed to do it, but it doesn't. I.don't.know.why.so.don't.ask.
