He sniffs and sniffs and sniffs. When I hand him a tissue he wipes the end of his nose and then continues to sniff. I've tried encouraging him "big blow!" And he will give a half-arsed attempt and continue sniffing.
He also sings terribly in a way that was endearing when we first met but now... Not so much... And he leaves his (underused) tissues in his pockets so the laundry is often covered in little white tissuelets. 
When we first met he had a proper programmed handkerchief and seemed to use it effectively and discreetly. Misrepresentation surely?
So I'm thinking dissolving in acid is the way to go re: the body.
