I was poking around in Selden's office looking for an envelope when I came across this handy little device. It is called an emasculator. The purpose of these "pliers" is to stretch an incredibly tiny "rubber band" which is hooked on those four posts at the end. Then you carefully place them over the testicles of any unwanted male animal in the barnyard (sheep, goats, pigs, steer), the blood supply is choked off, and presto within a month the offending gonads dry up, mummify, and just drop off! (Selden speculates - for any spouses reading the blog - that it could be used on a crotchy old Fossil who argues too much.)
