Can enyone hear ringing

So I'm sitting here loading my egg mayo sandwich with chilli tortilla crisps and thinking to myself:

Is it just me or can anyone else also hear a bell?
It's about this time I realise that it's the bell signalling that someone's stuck in the lift and I think:

Someone else will get it I'm sure and besides I don't want my crisps to get soggy.
And then hit me and I knew what I had to do.

I immediately hit youtube and dug up this video for your enjoyment:

Can't believe I'd forgotten about it. It's amazing what some things remind you of.


P.S. The bell's stopped now.
