Q: How does a cucumber become a pickle?
A: It goes through a jarring experience!

Explanation: Do you love pickles?  I do! 

Pickles are little cucumbers that are left in vinegar or brine for a period of time. This is usually done in jars. An interesting note: the process of making pickles is called canning (like, putting in a can) and not jarring.

Jarring is a word used to describe an experience that shocks or disturbs you; it is not a pleasant experience.  

This joke is funny because it plays with the word jar-cucumbers are put in jars, so, in a sense they go through a jarring experience.
