Here's a YouTube video of the recent class I held as part of WizIQs eltTechniques MOOC (it is still going on now and you can join to watch the sessions remaining live AND catch recordings of the ones passed)
Overall I rambled too much, but I covered some great ways to include jokes in your pronunciation lessons. If you are interested go ahead and give it a look. If you use jokes in your class to focus on teaching pronunciation in some other way I'd LOVE to hear about it.
Please get in touch with me, so I can learn form you :)
