The hypnotic joke

Well midway through my last post, someone came to talk,
I told him of the idea of a social virus.
He suggested the perfect medium,

a hypnotic suggestive joke.

i.e. a joke that hypnotises the individual and impresses on them the need to tell the joke to someone else.
This fulfills the 1st criteria of the virus, replication.

the second point is the payload......
Now this IS twisted,
it is that - the joke isnt even funny - but if you do it right - everyone will be telling it.

Given that the joke doesnt need to be funny and that its very unfunniness is the payload
The joke can easily contain a greetz in the punchline - something like
"Gorgeous Red Elephants Gamboling Over Recent Yards"
(take the first letter of each of the words of the punchline - it spells 'GREGORY')

Entirely unfunny punchline? Precisely!
