I just happen to find this symbol hilarious, primarily because 'interrobang' itself is a naturally amusing sounding word. For whenever an exclamation mark followed by a question mark would just look tacky. To, like, stir discussion, because stagnation is boring: aren't interrobangs awesome(interrobang) Alternatively: list some other amusing words. Go on. Do it. ~Jabberwocky

Well, what does an interrobang look like? I thought it was just a " ! " at the end of a sentande. Also, Translucidity, your words are not in my unabridged dictionaries, and therefore do not exist :)
A-ha, trying to floccinaucinihilipilificate my favourite words, are you? Just because your dictionaries don't contain certain obscure words of the uttermost compounded nonsensical natures doesn't mean such words don't exist. ~Translucidity
Mystery poster, an interrobang is like the creepy lovechild of ? and !; it has both the line and the curl superimposed over each other above the dot. - FourWillowsWeeping
