My GF once asked if we had the same moon abroad as we do in the UK, but what she was trying to ask was 'is it the same light' which is actually a credible question. But then went on to question why when driving alongside the see does its reflection follow you, which blew away any kind of normal question she may have proposed thereafter.

I also had a female friend ask about cows lying down before rain, we explained that alot of animals do it subconsciously even people. We then spend the entire weekend pointing out people sitting on benches and the heavy grey skys of edinburgh, we had her convinced it was true
