The Vet Solves a Problem

 

The Vet thought about this for a minute and asked, “Did you by chance, buy this cow in Illinois?”

The people were dumbfounded, since no one had ever mentioned where they bought the cow. “You are truly a wise Vet,” they said. “How did you know we got the cow in Illinois?”

The Vet replied with a distant look in his eye, “My wife is from Illinois.”
