Labour leader Ed Miliband dubbed David Cameron an "absolutely hopeless" Prime Minister who could not organise the proverbial event in a brewery today.
Mr Miliband seized on reports that the government has done another U-turn and is set to abandon plans for strict minimum pricing of alcohol.
"Can the Prime Minister tell us, is there anything he could organise in a brewery?" asked the Labour leader amid roars of laughter from MPs on all sides.
The Labour leader then poked fun at the beleaguered Mr Cameron over a claim by Communities Minister Baroness Warsi that the PM had the support of "large parts" of the Tory Party.
"Maybe he has even got the support of large parts of his Cabinet," quipped Mr Miliband amid renewed laughter.
Mr Cameron tried to rouse his backbenchers by reeling off a list of "dinners" involving Mr Miliband and trade unions in recent weeks.
"£2.7 million, dinosaur after dinosaur, dinner after dinner!" he ranted.
