Up to their eyes in...

The things people will do for money.  A French hospital advertised for donations of - there's no delicate way to say this - poo, and indicated that successful donors would be paid €50.  What it didn't say - or make clear - was that applicants would have to undergo "rigorous screening, interviewing and tests".  They have been inundated with so many people anxious to get their hands on €50 that they have had to suspend their (serious) scientific research.  The old saying "be careful what you wish for" springs to mind.
