MPs were a little blearly-eyed and subdued at PMQs today having spent a long night practising the tricky matter of withdrawal. The EU Withdrawal Bill that is.
Though in its way it is a method of political contraception, transferring all EU laws into British ones on Brexit Day to prevent an unwanted pregnant pause in our legal system.
Theresa May has got away with it so far, winning every vote last night but there is trouble ahead. Not in Prime Minister's Questions today though.
There was a curious reluctance to ask anything about Europe at all.
Jeremy Corbyn chose to remain close to home and he was concerned that Boris Johnson's police station was being closed. The PM blamed London's Labour Mayor Sadiq Khan for that.
The Labour leader then fluttered off on one of his butterfly question times asking one each on crime, Universal Credit, the NHS, schools and tax dodgers.
This is always a mistake. He is at his best forensically examining a single issue.
We were 27 minutes in before the EU got a mention. Tory Michael Tomlinson said something sycophantic and Mrs May agreed with him
Another Tory asked the PM not to allow East European rapists in after Brexit and Dover MP Charlie Elphicke wanted £1billion for his white cliff port to stop them.
The Withdrawal Bill is back again this afternoon, so perhaps MPs were storing up the fireworks until then
It is the biggest test of Mrs May’s premiership.
Lose it, and she might as well withdraw from the stage herself.
