Sebastian’s entry today about Politically Incorrect Toys brought back some old memories:

Interestingly enough, my neighbor worked for this very toy company, and they made all manner of politically incorrect toys, which we got to play with.  One, which I got to take home with me, was an automatic firing water pistol in the shape of an IMI Uzi.  It took batteries, because the stream was propelled by motorized action.  But it would fire as long as you held the trigger down, or until the (detachable) magazine ran dry.

I had one of these, too.  I can also confirm that it will shoot beer, although it tends to gunk up the mechanism if you don’t clean it out right away…
