Finally, someone got the joke.
It wasn't because, as was suggested by someone, that he's performing fellatio (it's a fish, people. Get your minds out of the gutter). The reason I chose Gollum was because that's how I read Klink's posts, in that Gollum voice.
Why that pic? It's the only one I could find with his head at the right angle to fit in that helmet. Oh, and it's funny.
Anyway, it was supposed to be a little light-hearted joke and blew out of all proportion because ... well, we're on the internet. It's what happens.
ps. Read Klink's gibberish posts in a Gollum voice and you'll see why it's funny. Life, my precious. Good, yes, yes?
