So I tell a lot of jokes, and some of them are just bad. But I think they are funny and it is important to keep the humor in life. 
I completely agree.  You have to laugh in life for health and happiness.  Ha ha, it doesn't matter if some of them are bad. I usually get the story or the dialogue with a joke but can't always deliver the punch line well. Sometimes those are the funniest jokes.

A joke is a display of humour in which words are used within a specific and well-defined narrative structure to make people laugh and is not meant to be taken seriously. It takes the form of a story, usually with dialogue, and ends in a punch line. It is in the punch line that the audience becomes aware that the story contains a second, conflicting meaning. This can be done using a pun or other word play such as irony, a logical incompatibility, nonsense, or other means
