Kerry reminds me of Gruber on the old McHale's Navy show. Gruber was always out to get a purple heart for the smallest scratch hoping it would get him out of the Navy sooner.
Carl Ballantine played Gruber.....
He was an old vaudvillian style act, as a magician.
Not only did he play the purple heart scam, he was always scheming. Very much like our F'in hero.
Another of McHales merry band was Gavin MacLeod who played Joseph 'Happy' Haines
Well, I never really watched that, but I can see a parallel with Corporal Klinger.
