Like yeah ok, for the first 5 five times one sees it, it's like haha, lol, there it is! But, these do get old really fast for me.
For me it's now more like -wow. So that is literally the entire joke? Like oof, I guess they really wannted to be funny.-
EDIT: Updated the funi image to actually be what I wanted it to be... Took me a while, sorry.
Yes. It's funny. It's the same kind of funny that "the game" (ha goteem), rickrolling, stick bugging the thing with the hand okay symbol, and even so far as "made you look" is. Just a simple easily spreadable and understandable "gotcha" to share with friends. It's constantly evolving and in a short time it will be something else with the same basic mechanism to be used as a gotcha and it will be funny too. Something doesn't need to be deep to spread a little laugh.
