If Lestrade Dies I'm moving to Wisconsin

So Greg is getting married!!!

John and Sherlock show up to Greg's place to throw him a surprise bachelor party to make up for missing John's.

He ADAMANTLY refuses. Sherlock keeps shoving a drink towards him and he resists as long as he can before at least taking a sip. John promises to keep Sherlock under control. Sherlock raises-eyebrows-cocks-head-smiles-innocently.

Greg looks flatly/angrily at him and says "suuure" and downs the entire drink to steady himself.

Greg relents and huffs, "Fine but I seriously doubt I'll be letting loose and enjoying myself fully with you two in tow. I'll be steadfast to have a peaceful stroll round a few pubs and be back by nine. Sharp."

Sherlock smiles and says "Mmmm, I seriously doubt that, seeing as how I've just spiked your drink with a healthy dose of ecstasy. You have about two to three minutes before you start seriously tripping balls."

Greg stares incredulously at the empty glass and then at Sherlock.

John rubs the bridge of his nose and groans out "Ssshherllll....."

Cut to a montage of hijinks set to the entire song Brass Monkey by the Beastie Boys.

Greg standing on a crowded pub bar leading everyone in a drinking anthem, wearing a leather jacket.

Where did the jacket come from, nobody knows.

John trying to pay the management off from calling the cops.

Sherlock egging Greg on to jump in a fountain.

How did they end up at a frat party.

John trying to talk him down from jumping in the fountain.

I don't think that was just ecstasy.

Greg and Sherlock beating frat boys at beer pong.

Greg is now in the fountain.

All three running from the frat house to escape angry drunk dudes.

John pushing Sherlock into the fountain.

Greg waking up wearing Sherlock's coat and spooning a decorative shrub.

Someone: why are you crying?what happened?
