For all your unanswered questions:
This is Jack Klugman: actor, author, and divine muse. Obviously, you have excellent taste in character actors since you are visiting this site.
This is Mike Sterling, comics blogger, teen idol, and all around swell guy. Not the kind of guy you want to tussle with. Almost Klugmanian in his demeanor.
This is Gordon from Blog THIS Pal. We do not know what his problem is, but wish he had a better picture on his blog. Other than that, relatively harmless.
Finally, this is Cantinflas.
Hope this has helped, and thank you for visiting.
