A Physicist, a Mathematician and an Engineer are stuck in a room with a Lie Detector

Since as early as I can remember I get the following pairs of letters muddled up

'p' and 'b'

'd' and 'g'

and others I can't remember right now
It's like some mild disability

If we're just turning this into a maths joke thread:

One Spring morning, a mathematician goes to meet his engineer friend at a coffee shop. He waits, and waits, but the engineer doesn't turn up.

Eventually, the engineer strolls casually in, an hour late.

The mathematician says 'What took you so long? You remember we put the clocks forward yesterday?'

'Damn, are you sure?'

'Yes, it's trivial by the AM-GMT inequality.'

I'll get my coat.
