Searching For Mister Stewart

We got on the subject of an old dog from the past, one side of the family, from the '70s. His first name was Mister and his last name Stewart.

But we can't remember when he died, or even if he died, although of course he did and would had to have long before now. There aren't dogs that old.

Yet there's no memory of his death, so I suggested, we put an ad in the paper, "Searching for Mister Stewart," and see how many Mr. Stewarts reply.
