The majority of people are able to experience humour, i.e., to be amused, to laugh or smile at something funny, and thus they are considered to have a sense of humour. The hypothetical person lacking a sense of humour would likely find the behaviour induced by humour to be inexplicable, strange, or even irrational. Though ultimately decided by personal taste, the extent to which a person will find something humourous depends upon a host of variables, including geographical location, culture, maturity, level of education, intelligence and context.
For example, young children's sense of humour may favour slapstick, such as Punch and Judy puppet shows or cartoons such as Tom and Jerry.

When someone either finds an obvious joke offensive or takes it dead serious, they are said to have had a "sense of humour" failure.

However, it cannot be applied to those who never had a sense of humour to start with.

This condition is more common amongst the grumpy, tired and irrationally angry sects of society, with the most common manifestation being women on their period or guys whose girlfriend is on their period.
That easyJet lady had a sense of humour failure when you asked if your "little" 16 year-old son counted for the priority boarding.

I don't think so. I think she had no sense of humour to start with.

Yeah, or it is that time of the month for her. That could explain her sense of humour failure.

When someone has taken a joke the wrong way and their expression on their face is all you need to confirm this. This can also be applied when due to being in public (e.g. live TV or in front of friends) they can't say they are annoyed but they can't hide it from their facial expression.
