PSSST . . . wanna buy a ticket to the Rugby Sevens? If you know a student at the Island School - or better still, a parent who has a child at this academy of excellence - you have a good chance of obtaining tickets as long as you are willing to fork out above the odds. My information is that resourceful pupils from the fifth and sixth forms at the Mid-Levels seat of learning (and entrepreneurial flair, it now seems) teamed up and queued overnight to gather a lucrative wad of tickets which they are now flogging off - the asking price late last week was $1,000 for a ticket with a face value of $320. And buyers there are aplenty. One captain of industry apparently bought four tickets through his student daughter - who in turn negotiated a small commission from the seller. Like most sensible expatriates, I dispatched my amah to keep an overnight vigil at Victoria Park and buy the precious quota of two tickets per person. But I'm not quite sure what to make of the tale she came back with about lining up alongside 10 Thai girls who had apparently been hired to queue up by a multinational (the one claiming that its product is ''The Real Thing'') which was 20 tickets short for corporate entertaining in its privileged box. But back to the Island School. I suggest that headmaster David James hunt down the teeny scalpers and confiscate their supply of tickets (administering a stroke or two of the rod while he's at it would be in order, too). Armed with the prized tickets, he could invite a few friends to join him for an enjoyable (weather gods permitting) day at the scrum-fest next month. Which reminds me, I need an extra Sevens ticket or two as well. Let me see, who do I know with offspring at the Island School? Ah, yes. ''Hello, Government House?''
