That Time Louis Whispered into Harry's Mouth

I know human anatomy can be confusing. We've got all these parts and appendages and who knows what they all are there for. Like do we really need a spleen? And randomly, my friend has 4 kidneys - maybe that's where Liam's kidney missing kidney went for awhile! Anyway, this one time, during a concert, Louis decided to whisper something to Harry, but he got lost along the way and whispered into his mouth instead. Oops.
