Yes, Curt, my humor can be very immature. I blame teaching teenagers for almost 40 years for it. That and my habit of running things into the ground can be quite irritating to others. Most of my family and friends ignore me and move on, but I know they heard me and smick to myself. Yes, "smick" is one of them, too. I got it from Tommy's saying, "Just you smick, Dirkie Smothers!"
There are some things I say that I never get tired of and always find amusing. Is this some kind of disorder? Probably. The main thing I like to do is call those plastic wrappers around newspapers "newspaper condoms" and usually just leave it at that but sometimes mutter "for safe reading" afterward. I still think that's funny but probably need to save it for new audiences because I've exceeded my limit with several friends.
I had to retire "it must be free" when the price is not on items in shops. Salespeople never thought that was funny except for maybe two of them. They always corrected me which takes away all the jokiness in a situation when others take the statement seriously. This also happens sometimes when I say Norwegia and Canadia. You just have to let them think you're a dithering dumbass because if you have to explain a joke, it's not worth it. Right?
