That joke is as bad as mine was!
To be honest, the joke I actually told in that meeting was different to the one I said in this post and one I can't/won't repeat I writing publicly. It wasn't much better than the one in this post to be honest, but it had the desired result nonetheless.
It's bad, isn't it? hahaha
What matters is the result, relaxing people and the good mood to continue the work.
