Puerile schoolboy humour

Prime Minister's Questions, yesterday:

Dave just can’t help letting himself down, either with the failure of his internal logic – employers have been gagging to get rid of tax credits so they can increase salaries – or by being a sucker for a bad gag.

“You don’t want FFA, full fiscal autonomy,” he sniggered at the SNP’s Angus Robertson, “You want FFS, full fiscal shambles.” FFS! Dave had got FFS into Hansard. High fives and lols all round in Downing Street. Coming next week, WTF. Working Tax Fraud.

Pretty pathetic.
