Last week the Anarchist Studies Network email group ran a series of Anarchist jokes.
These were mostly pretty obvious 'How many Anarchists does it take to change a lightbulb?' 'None - the lightbulb must be smashed' but I rather liked this one.
An Anarchist, Trotskyist and a Stalinist each go home and find their partner in bed with someone else.
The Stalinist shoots them both.
The Trotskyist goes into another room and writes a 6000 word denunication of their act and calls for a split.
The Anarchist jumps into bed and joins them.
You can find more of this harmless nonsense at Riot Joke.
