The first photo here is of one of Dad's teaching (and fishing) partners for many years - now retired. They were both given wrapped gifts during Dad's party that they were required to open simultaneously . . . because they both contained loaded water pistols!
Apparently, one of the teachers had a strong memory of Dad and this other "Mr. S" closing out one particular school year with a water gun fight in the halls of school after the kids were gone that last day of school!
Now that's one I'd have to have SEEN to believe! ;)
