Humour with a bite or edge to it, often involving some form of thought or analysis to really get or understand. Often used to teach or inform, much like satire or subtle sarcasm.
"People often say that I'm not very funny. I am, I just use straight-laced humour. Life's too full of nonsense as is for me to crack a joke without some form of thought put into it..."
