The Big Lebowski movie has a part where a ferret is throw into the
bathtub with 'The dude' as a threat .  Haven't watched it for a long
time, but 'the dude' kept referring to the ferret (common sable) as a
marmoset.  By the way, he did seem quite terrified having a ferret in
the tub with him, swimming straight for his, uh, privates?!
