A/N - Kids, this is why drinking is bad;)
John stumbled into the kitchen (clearly suffering from of the hangover from the night before) white faced and shaking.
"Sherlock," John mumbled, "I seem to have accidently got married."
Mycroft (John hadn't bothered to ask why he was visiting, it was always best not to interfere with the Holmes brother's arguments, especially when your head felt like it was going to explode) looked faintly amused and raised an eyebrow.
"This woman–Mary? Just rang to say I proposed to her last night, she's got evidence, and we went to the registry office and everything. I thought this sort of thing only happened in Vegas."
John looked at Mycroft. If it had been anybody else they would have currently been rolling around on the floor in hysterics, as it was Mycroft merely had a small smirk. In any other circumstances…but he was desperate.
"Mycroft, if you sort out this mess, Sherlock will take any case you give him."
Sherlock made a noise of protest. John gave him a glance that said 'don't worry, I'll give you something in return if you just behave for once.'
Mycroft inclined his head and turned to go as John whispered, "Please at least try to make it an interesting one. For sanity's sake."
"Rest assured, I'll do my very best."
