As one of the ritziest cities in the Valley, Scottsdale has more than its fair share of glitz and glamour. And depending on who you talk to, it also has a little bit of tastelessness.

This was most certainly the case this past weekend when a few people celebrating the scary season adorned themselves with over-the-top costumes that challenged the boundaries of good taste or were flat out offensive.

Here are five outfits that we spied at various parties and events around Old Town Scottsdale that were the best of the worst.

5. Osama Bin Laden This chap, who we spotted at the "Nightmare on Princess Drive" party at the Stone Rose Lounge in North Scottsdale apparently didn't read our blog from 2011 chronicling the offensive costumes we spotted in Scottsdale, as we specifically cautioned against Caucasians dressing as Middle Easter terrorists. He decided to spend his Halloween clothed in the robes and turban of one of the most notorious Al Qaeda members ever, the late Osama Bin Laden (a.k.a. the mastermind of 9/11). At least he had enough taste to refrain from adorning the costume with blood and bulletholes. 4. The Fifty Shades of Grey Guy

E.L. James' ultra-trendy BDSM novel has been read by millions of women across the world, including many a bored housewife or wallflower throughout the Valley. This one gentleman, who was in attendance at the annual "Nightmare on Princess Drive" at the Stone Rose Lounge in North Scottsdale was probably hoping to come across one or two ladies who'd flipped through the pages of the erotic potboiler. As such, he was wearing a large cardboard box that resembled the tempestuous tome that opened up to reveal a number of sexual...uh, accessories, including handcuffs and a cat-o-nine tails. The anal beads might have been a bit much.

3. The Walking Eecard It seems like everyone and mother has sent at least one or two of those extremely humorous - and extremely popular -- EEcards to their friends or family (or posted them on Facebook). So it came as no surprise to see someone create a Halloween costume out of one. While this fellow at the Axis/Radius Ghostball Block Party gets points for creativity, he might have wanted to choose a less offensive card to depict. We're certain that utilizing a hammy dick joke ("You like fitness? Well how about fitness dick in your mouth") that's a favorite of stand-up comic everywhere ensured he went home at the end of the night all by his lonesome.

2. The Giant Douchebag Its been said that Old Town Scottsdale's nightclubs and bars are filled with douchebags. This cat at the Axis/Radius Ghostball Block Party decided to take things a step further and transform himself into a literal version of the term, or at least his approximation of one using a large trash bag and a number of feminine hygiene products.

1. The Walking Penis We encountered this gentleman (and we use that term loosely) outside of El Hefe on Saddlebag Trail. Undoubtedly, we can state that his costume of a ginormous male member - complete with a certain bodily fluid - was the most offensive costume ever. He let us grab his picture, but we gotta say he was a big dick (literally).
