Are we to politically correct or just over sensitive?

[Kendo]

We have a laugh at work.

Italian concreters.
Irish and South African engineers.
Kiwi pipe layers.
Kiwi and a Welsh directors.
English secutary.
Brazilian HR guy.
English, Maori, Scottish labourers.
Irish traffic controllers.

It's just the Aussies who we have trouble getting to do any work.

Ok, great mix of blokes. Now a question of this thread.
Does everyone give each other shit and take the piss in that normal blokey way, or is everyone too concerned about being PC to have a bit of fun.
