The 60 second Orgasm
Hark back to the days of windows 3.11.. If you had a startup sound it had to complete playing before relinquishing control back to the user. We added the 60 second orgasm scene from "When Harry met Sally" to our manager's desktop. As it happens he had 3 visiting managers from head office who ended up outside the office laughing so hard that one neatly wet himself.
