Hey Izak, Welcome. I don't have a joke for you but why not find some posts of interest and make a comment. Then you'll be part of the thread and will be notified when someone else posts. The more you post, the more you'll interact with others. If you want laughs, the fun and recreation area works very well!!
And if you find you no longer want to be part of a thread, just unthread. Hope to see you around!!
