Ideas on collecting tears from mice!!??

[Naseco]

I am an undergrad working in a research lab and am looking for any ideas on how to collect tears from mice for one of my projects. I don't want any surgery tactics or anything.

Since the chemistry of tears varies by what causes them -in humans at least, as I have heard-, you may want to tell the mice sad stories and jokes as well as subject them to irritants. (Not to presume sad stories and jokes won't irritate the mice of course. )
