Othello (or O., as the kids are calling it these days), is ostensibly about revenge (or racism, as any collegiate Shakespeare survey course worth a damn will tell you), revolving around Iago and his plan to unravel the titular character. Said plan is devious and complex, involving multiple moving parts and perfect timing. I haven’t read it in a long, long time – and I haven’t even thought about it since I was dozing off in the back of forementioned Shakespeare survey course worth a damn – but I do remember that things end up pretty badly for all involved. And that there was something important about a handkerchief.
Anyways, this prank is kind of like that.
