I was in class today (monitoring my beginner adults taking a test) and ended up jotting this down with many, many scribbled notes next to it). It origninated as a bunny from tf_bunny_farm. Bunny was #32 from this post.
Sam: Constructicons? What are they?
Sam: Yeah, I got that part. What with the trying to kill us, the red eyes and the teeth, but what are they?
'Bot: The teeth?
Sam: Yes, the teeth!
'Bot:.... of all the things to fixate on you chose the teeth?
Sam: Hey! "Con holds you that close to his mouth of course you're going to notice the teeth! But anyway, off topic. Constructicons. What are they?
'Bot:... a Decepticon sub-faction and Gestalt.
Sam: Sub-faction, Gestalt? Huh... wait! They turn into construction vehicles... Constructi..cons... construction Decepticons? Isn't that a bit of an Oxymoron?
'Bot: ...quite possibly.
Sam: *cracks up laughing*
'Bot: *isn't sure he wants to know*...what?
Sam: I wonder if they beep in reverse.
'Bot: ... Beep?
Sam: Yeah, beep. All construction vehicles beep when they reverse.
'Bot: .... *starts snickering*
The bunny was When in vehicle mode, do the Constructicons beep when in reverse?
And, yes, this will eventually be written in a proper fic format. I just had to get that conversation onto paper before I lost it.
