REVISIT, & WRITE MORE FUNNY
REVISIT: If you really want to punch up your comedy you HAVE to revisit your jokes, thoughts and bits many times...many many times...yes even those that are working. Creating a joke is one thing. A willingness to consistently polish, hone and do a fresh mind revisit to that joke/jokes can assist you in writing even more solid punch lines in addition to what you already have. If you practice this the likelihood that you will break new creative ground and begin to expand on your subjects is high.
