I am naturally not a funny person and so I could always use some inspiration for clap-backs. 
However there where maybe 10% of the jokes that I could or would use in real life and actually laughed about. I had trouble really connecting with most of the jokes and naturally not all situations apply to me or my life. 
I do still think categorising them by "situation" is a really good idea. 
If it's worth the money? I have to leave that up to you.
