One of the cultural highlights of the Labour election campaign has been the emergence of the Corbyn Jokes twitter feed - sample joke "I'm not saying my mother in law talks too much, but last week I read the first four volumes of Marx and Engels private correspondence whilst she was on the phone". There are also some great variations on the "Yo Mama's so fat" jokes beloved of Eddie Murphy.
For those who do not think there is enough humour on this site, here is Corbyn Jokes on conspiracy theorists:
