Having a quick and ready joke can be useful to have.
In some cases they are difficult to retain unless you share them with others.
A simple, clean, direct and fun joke are generally not overly difficult to retain.
Simply share the joke with others and you might even want to write them down if you are attending an event, going out and even if you are heading to a gathering of some sort.
Each of these jokes is clear, clear and to the point.
Have some fun with them!
