Sons of Accountancy

The name of a motorcycle gang consisting entirely of middle aged, mid life crisis-torn, middle management fat men, who spend their working weeks chained to a desk answering purchase ledger queries, but have saved enough to buy a Harley Davidson, on which they ride every weekend, pretending to be an outlaw.

Me: What you up to this weekend Dave?
Dave: I'm going to ride the Harley around Midlands towns with the gang.
Me: You crazy Sons Of Accountancy.
