THE QUESTION:
YugDung: Why are 18-Wheelers(which are big trucks, if i'm not mistaken) reffered to as semi's?  I would call them wholes, my self.  And if they are semi trucks... Then I don't want to see the whole truck.  Unless it had knight Rider in it.  Then i'd be cool.  Because Knight Rider was awesome.  Even if it did have the same main character as Baywatch.  Don't totally write off Baywatch, though.  Without it we would never have known the hilarity that can be attempting to run in slow motion.
THE (awestruck) ANSWERS:
Megalo15:  No freaking clue...maybe they're only semi-legal vehicles because they're so big...like the hummer?
Got me!

(Big like the hummer, or illegal like the hummer?  Cause last i checked those big ass hunks of metal were still taking up way too much road space, and nowhere near enough four wheeling space.)
LilMangaGirl: They are? ....hm. Why does this bother you so? I didn't even know. This is the most random question. Almost beating [Valdreag]s genitailia.
(Darn... I really thought i'd beaten Valdreag's genitalia...  Oh well, back to pills...)
(My genitalia will never be beaten. Ever.)-Valdreag
(That was lame.  Excessively so, if I may say so.  You could've at least thrown in a joke about length or the motion of the ocean or
something!)-YugDung
isisincognito:  First, let's decide what semi- can be a prefix for. semiarid, semiautomatic, semicircle, semicolon, semifinal, semiformal, semiliquid, semigloss, seminude, semipopular, semisolid, semisweet, semitropical... I could go on for days. Secondly, let's all go out for ice cream and tomfoolery.
(Woah.  You can't mix Ice cream and tomfoolery.  Not unless you want
semitomfoolery.  And noone wants semitomfoolery, trust me.)
Iohnus Albus, Master of the Anything-Goes Final Fantasy Sword Fighting School of Martial Arts and Wizard of the 30th Circle of Solusek Ro.: It is because the real trucks are the smaller trucks with I think 8 or 10 wheels.  Therefore, the 18-wheelers are not real trucks, but are Semi-trucks.
(Wow.  That actually makes sense.  In a totally illogical and counterintuitive manner.  God the world is screwed up.)
Reverend Two Sheds: Hilarity of the slow motion run? Sweet Jesus man, its not a humorous thing, its blessing that shouldnt be laughed at. Besides, Im too busy moving my eyes along with the motion of the swinging ocean to laugh, no time now, boobs are a priority. Wait, your a Eunich YugDung, you will have to go talk about trrucks else where during the slow mo time, you arent entitled to see their nipping glory.
(Why's it always got to be about my absence of penis?  I have a dream... a dream that one day we will throw aside our genitalia.  Man and woman will unite as one through their mutual exclusion of "low and swingers".  And then on the seventh day, we'll pull a trojan horse like manuever, sew them back on, and rape the women (and hell, why not the children too?) in their sleep.)
(Wow.  I've officially crossed like 6 lines at this point, huh?)-YugDung
(Besides, I already told you, my genitalia simply cannot be beaten. Bitch.)-Valdreag
