So What Is A 'Laughter Therapist'?

So what makes a Laughter Therapist?
Qualifications?
Experience of fringe theatre/the stand up scene/radio/tv appearances?
The ability to tell jokes to your mates down the pub or at work?
Well all of the above and many more examples could be given... but to me, a Laughter Therapist is best defined as:


Someone who can help you to laugh!
Straightforward and unbelievably simplistic I know... but is it? How many people are able to do that?
If you can think of anyone who you think is a potential laughter therapist (including yourself) and would like to see 'em get a mention here, send an email to me and let me know.
