I like to think this sums up the level of humour, and perhaps the love-in that is their relationship... 
CORDEN AND HORNE ARE ALONE IN A ROOM. IMAGINE THEM GETTING INCREASINGLY EXCITED AS SKETCH PROGRESSES.
CORDEN (LOOKS AT HORNE): I've got the horn
CORDEN (TOUCHES HORNE'S HAIR): I've got the horn
CORDEN (LICKS HIS FINGER AND RUNS IT DOWN HORNE'S CHEST): I've got the horn
CORDEN (PUTS ONE LEG ROUND BEHIND HORNE, WHILE STILL STOOD UP): Oooh, I've got the horn
CORDEN (LICKS HORNE'S EAR): I've got the horn
CORDEN (STARTS PULLING HORNE'S SHIRT OFF): Hmmm. I've got the horn
HORNE RIPS SHIRT OFF, REVEALING NIPPLE TASSLES AND FAT. LOTS OF FAT. HUGE AMOUNTS OF FAT.
CORDEN: I've got the horn
HORNE (PLAYS WITH TASSLES): (WHISPERS) I've got the horn
CORDEN: I've got the horn
HORNE: I've got the horn
HORNE TAKES TROUSERS OFF
CORDEN: Oooooh. I've got the horn
CORDEN AND HORNE RUB UP AGAINST EACH OTHER
HORNE: I've got the horn
CORDEN: I've got the horn
(BOTH PANTING. KISSING, RUBBING)
I've got the horn.
I've got the horn
I've got the horn
Ooooh
Aaaahhh
Hmmmmm
Sigh
Sigh
You were great.
I know.
