Having successfully completed its passage of the House of Commons, the Government's Same Sex Marriage bill enters debate in the House of Lords today.
Observers expect this part of the passage to be every bit as excruciating as it was in the Commons, where MPs competed to see how hysterically offensive they could be.
And the Lords have plenty of "previous". The Hansard accounts of their debates on issues such as equalising the age of consent, introducing same sex partnerships, and the Gender Recognition Bill are not for the faint hearted. The new debate kicks off with consideration of a wrecking motion by one peer to not even debate the legislation at all.
If you are planning to listen to the Lords debates, you might as well settle back with some popcorn, and fill out this handy bingo card produced by campaign group Stonewall. See how many specious arguments you can spot.
