Imagine Tonks during her years at Hogwarts making herself look like Dumbledore for no real reason other than to confuse the hell out of other students by plopping down next to them and asking them weirdass questions like if they've ironed their socks in the last week and then walking away
Imagine Dumbledore realising she's doing it and joining in so that sometimes there are two Dumbledores talking to one student.
