Categorise Puns

No jokes here, just a request for some help/clever words. (admin - delete if you're looking just for jokes).

My 12yo son has decided to do a school speech on dad jokes! He is attempting to categorise different types (in a comedic way if possible), Herding cats is easier.

As a Dad my joke are funny (mainly just to me) and off the cuff (so no use in a planned setting); I am requesting some help from those dads more wordy than myself; looking to impart sage words.

Any help will be appreciated and if the speech goes well i will post it.

thanks in advance
