The homies over at vice.com have put together this really weird section called Dos and Don'ts. I have selected some of the funny ones and have taken the liberty to add some commentary on the situatinos to help out those who do not know any better.
Don't Do This, or Do Do This.
If you are a pirate DO always have at minimum two bar wenches with you. Extra points for a full chorus line of wenches.
If you are awesome enough to wear a Vader costume, DO rock a once piece bathing suit while you are at it.
For the youngters, if you are going to rock the stoner/punk/biker look DO it in front of a McDos posted with all the cuties.
If your friend happens to be picking her ass in the middle of the street, DONT let the photographer get away with a full set of teeth.
