And she'll have fun, fun, fun, till her Daddy takes her teapot away...

The consenus is in, and it's notion!

See, for years and years and years, I was convinced them Beach Boys opened their song with:
"♪ If everybody had a notion, across the USA, then everybody'd be surfin' ♫"

Which makes sense, coz it's talking about everyone in the USA having the same idea (or notion, if you will) to go a-surfin'.

Now, some peoples dispute this, and claim that it's actually:
"♪ If everybody had an ocean, across the USA, then everybody'd be surfin' ♫"

Now THAT makes fuck all sense! If everybody had an ocean across the USA, there'd be now BUT ocean! And then they'd all drown. Or be et by sharks. or something.

Of course, if you search t'internet, it'll come up as Ocean - but that's because the interweb is written by gormsters who just put up whatever old crap they hear - even if it's totally against the official lyrics put out by the band!

Anyhoo, I reckon it's not "♪ If everybody had a notion ♫", "♪ If everybody had an ocean ♫", "♪ If everybody had sun lotion ♫" or even "♪ If everybody had Snape's potion ♫"¹.

No, not at all.

I reckon it's all about some oirish strumpet, begorrah where's me gold y'english bastid leprechaun clover guinness potato to be sure bejaysus:
"♪ If everybody had Anne O'Síán, across the Emerald Isle USA, then everybody'd be surfin', but not the ocean waves ♫"

If you know what I mean, and I'm damn sure you do. Horizontal surfin', in the dunes with sand in yer snatch and clogging up yer jap's eye. And if everybody across the USA has had her, no wonder she's all clogged up! Emerald Isle? Emerald Isla Of The SS, like a Blue Waffle. probably. or not. as the case may be. or something.

Although I could be wrong...

¹ AND NOT, AS SOME POTTERERS WOULD LIKE, "SNAPE'S PORTION". STILL, IF SNAPE'S SLIPPING YOU A LARGE PORTION, AT LEAST IT'S NOT VOLDERMORT'S NAGINI INTERFACING WITH YER ORIFICE. OR SOMETHING. WHAT WAS THAT BIT IN THE CHAMBERPOT THAT SECRETES? OH YES...
“VOLDEMORT'S SNAKE, NAGINI,” SAID PIDDLE SOFTLY, “IS MY PAST, PRESENT, AND FUTURE, HARRY POTTER...”
HE PULLED HIS TROUSER SNAKE 'WAND' FROM HIS POCKET AND BEGAN TO TRACE IT THROUGH THE AIR, WRITING FIVE SHIMMERING WORDS:

SLIMMER DILDO, NO VAGINA ROT

THEN HE WAVED HIS WANG ONCE, AND THE LETTERS OF HIS NAME REARRANGED THEMSELVES:

I AM LORD VOLDEMORT'S NAGINI”
