Not only are they so stupid that they think this is some backbreaking work of labor to put up (it looks great, but it's what, a half hour to an hour's worth of work?)

But on top of that these assholes are so fucking internet addicted they cannot even fathom the idea of asking a friend or neighbor for a hand putting up decorations. 

 Or that you don't even need to ask, maybe the neighbors offered a hand to put it up on the own accord so the street looks nice for the kids.
