NOKW - Hot Tub Time Machine

Here comes the next chapter in our "I'm Okay With, I'm Not Okay With" series (if you don't know what this is, click here for all of the past posts):

Movie:  Hot Tub Time Machine

Basic Plot:  A group of friends go to a crappy ski town for some time off and magically travel back in time to 1986 where the hi-jinx ensue.

I'm Okay With:  The fact that the main characters would even hang out with Lou because he is a huge dick and might be the worst friend anyone could have.  The fact that Clark Duke's character is John Cusack's character's nephew but for some reason he lives in John Cusack's basement even though we know that Clark Duke's mom is alive and well.  The fact that a Russian energy drink is the key to making the time machine work.  The fact that I'm pretty sure that Chevy Chase is the one running around in the bear costume and no one else figures this out.  The fact that when Lou stays behind in the past and doesn't travel back to the future with everybody else, the entire course of history does not change other than he is now the founder of Google (now called Lougle).  The fact that when everybody but Lou shows up in the future, all of their friends and loved ones are cool with it even though every memory that they have does not match up with the current timeline and in essence, they are not the people that the future people know at all.

I'm Not Okay With:  The fact that only the main characters are supposed to travel back in time while in the hot tub but somehow their clothes and skis travel back in time with them.  Basically, they travel back in time due to the hot tub and when they wake up the next morning, they get dressed in the clothes and use the skis/snowboard that they brought with them.  But how?  If only the stuff in the hot tub traveled back in time, how is it possible that their clothes and skis traveled back in time with them?  We know those things weren't in the hot tub with them because they wake up in their underwear the next morning.  They were not in the clothes they brought with them and certainly they were not wearing their ski equipment, so how did that stuff show up in the past, too?  Obviously the answer is so that our time-traveling pals don't figure out that they traveled back in time until later in the day, but even then you would think that they would have noticed all of the 80's stuff way earlier then they did.  I am not okay with that.

"This Lyndsy Fonseca, she played the hot chick who stabbed John Cusack in the eye with a fork.  Did you know that she is also the girl who plays Ted's daughter in How I Met Your Mother?"
