If your mum wouldn't do this for you then she doesn't love you. (Not really)
While some might say this is a sign of true maternal love, we think it's a little creepy. Anyway, this unfortunate Serbian woman only rocked up to the wrong school, sucked off some random bloke and left without her dignity or indeed better grades for her son. Fair play to the teacher, though. He didn't mind. We imagine it went something like this:
'Are you Mr Markovic?' *undoes button*
'Umm...Yes, yes I am...'
