Jarvik is perhaps best known to the public for his role in helping to develop the Jarvik-7 artificial heart.

The subpoena arose out of a lawsuit in which the labor unions sued Pfizer, claiming their health benefit programs paid for Lipitor prescriptions that were written for patients who should not have received them.

Pfizer claims the subpoena is baseless.

The litigation is another example in a series of unrelated legal maneuvers in which lawyers have attempted to hold celebrities accountable for the things they say in ads.

The Federal Trade Commission is currently reviewing celebrity ad endorsements to see whether stars need to make greater disclosures regarding what they say about products (Brandweek, April 2).

That review was spurred in part by various pharma marketers' histories of using celebs to talk about drugs on TV talk shows without disclosing that they were paid to do so.

And the FTC lost a case a few years ago against baseball player Steve Garvey, who had hawked the fraudulent Enforma weight-loss system in late-night infomercials.

The Lipitor suit hangs on the arcane language that details the segments of the population for which the Food and Drug Administration approved Lipitor.

One segment ...

We're choosing venues in turn and Caroline has picked The Drawing Room in Laburnum Street, Bethnal Green.

It's a good first stop - the gallery is auctioning drawings by artists such as Cornelia Parker and (of course) the Chapmans, with bids starting at £150.

But it turns out to be further away than we'd thought and Caroline is wearing the sort of shoes you wear when there's a chance you'll bump into Jake or Dinos.

Also, Laburnum Street isn't as leafy as it sounds, being what my grandmother would have called " rough".

Still, the work on the Drawing Room's walls is good.

My choice next, and it's off to Hotel on Old Bethnal Green Road.

East End spaces often have cheeky names - one is called f-art - and the work they show is commensurately playful.

Until 9 May, Hotel is host to Torsten Slama, an Austrian whose visions of a post-industrial apocalypse seem oddly suited to the area: The Secret Missile Silo could be one of the slab blocks just visible through Hotel's windows.

Caroline is now regretting her Manolos on various counts, pain and muggability being but two.

Also, it's three hours since we left the Whitechapel and we haven't seen so much as the Chapmans' dog.

So we head south east, to the cluster of galleries off Cambridge Heath Road - specifically, to Herald Street, home to a space of the same name of which we have heard good things.

I do not at first register the subject of Cary Kwok's work.
