Bill Weasley is an evil, evil man. Therefore
he is the one you should blame for unleashing drunken Weasley twins upon the bar.
The very first thing they do is stand upon a table, and get ready to sing. What they sing about, is, of course, Quidditch. In very loud voices. That are out of tune.
The song, is, of course, quite indecent.
Build a bonfire, build a bonfire
Put France on the top!
Put Spain in the middle
and burn the fucking lot!
Build a compost heap, build a hee-eap
Put Bulgaria on the bottom!
Put the Swedes in the middle
And the kiwis can go an' sod'em!
Pass the Quaffle, pass the quaffle!
Beat those bludgers at their faces!
Send a wink to the pretty ladies,
And everything will be aces!
Pass the beer, pass the beer,
Pass the beer around the room!
Then the ladies will simply love you,
And go for rides on your broom! Feel free to heckle. Or alternately...
"Any requests?" George calls out, laughing so hard he might fall off the bar.
Also, please note there is a tray of treats on bar counter. It is quite innocuous. And there is a note there in Val's characteristic green ink that says:
I made some snacks for everyone. No reason really; I just wanted to treat you all. Help yourselves and please don't be greedy!
Love, Val. Yes, bargoers.
Help yourselves.
And have your hair turn purple and turn into giant canaries.
