Comedian Dan Antopolski has gone from most to least humorous in just 12 months.
In 2009 the Petah Tikvah-born stand-up won the Dave trophy for the funniest joke of the Edinburgh Fringe.
But this year he was awarded the honour of having the “worst joke” of the festival.
His gag went: "How many Spaniards does it take to change a lightbulb? Juan."
It was not deemed as humorous as his previous effort, which went: "Hedgehogs - why can't they just share the hedge?"
