Stock Watch: Back when orders were sent verbally on the trading floor, did errors ever erupt 'I said buy not sell', etc.?

I couldn't find this by searching, but from watching old movies I used to see the circles on the trading floor where stocks or commodities were traded, and with all the shouting there had to be mistakes made I am sure.

I was just wondering if anyone ever went through that, was it common and how it was it handled.

Thanks
