Some products out there have the ability to sell themselves, while others could use a little help. So, it's no surprise that companies regularly turn to a well-known face in an attempt to bump profits up a bit. But sometimes, the choice of celebrity can do just the opposite. The celebrity might end up in some trouble or maybe they just really weren't all that well liked to begin with. Either way, here's a list of a few items we should never buy simply because of the celebrity that endorses them.

7 Ashton Kutcher – Nikon Cameras
That damn Kutcher. We finally manage to get him off the small screen and out of our homes when Nikon has to go ahead and have him pop up even more regularly than before. The only way to make it stop is to not buy their products. Also, ladies, if you could stop going to see those horrible romantic comedies he stars in, we might be able to get rid of him completely. If we all work together, we can once again live in a Kutcher-less world.

6 Jenni "JWoww" Farley – Australian Gold Tanning Products
The world would be a much better place if Jenni "JWoww" Farley were just a torso. But, since she has a head, she has the ability to be a spokesperson. The only product we should support JWoww endorsing is an issue of Playboy magazine. Until that day comes, stick with any other suntan lotion or take your chances with melanoma.

5 Justin Bieber – Proactiv
The kid's barely experienced puberty, so what does he know about acne? And even if he does know a thing or two… how clear does your skin have to be when you've got hair covering the majority of your face? I think using people with seemingly flawless skin is always a bad move with these products. Proactiv should, instead, look into getting Edward James Olmos and just threaten people that if they don't use Proactiv that could be their future. Fear sells. Why do you think there are 17 Saw movies?

4 Michael "The Situation" Sorrentino – Devotion (protein-infused) Vodka
Reportedly, Michael "The Situation" Sorrentino is set to make around five million dollars this year. How's your 50-hour work week going? Forget the fact that protein and alcohol pretty much cancel each other out for a minute and ask yourself, "Do I really want to be responsible for contributing to his income?" So, we probably shouldn't buy this product. Keep your protein and booze separate, people. It doesn't make any sense anyway. It's like wrapping your carrot and celery sticks in bacon.

3 Lionel Richie – Walkers Crisps
Oh Lionel. You've given us some of the greatest, cheesiest, and most romantic songs for our seducing pleasure. Is nothing sacred? Now whenever I pop in one of your CDs for a girl, she gets hungry… not horny. You've ruined this for all of us. We counted on you. From now on, when we intend to make sweet, sweet love to a woman on a bed of rose petals by candlelight, we're gonna have to go ahead and turn to Michael Bolton.

2 Chris Brown – Got Milk?
It's probably not the best idea for a product that promotes growth and strength to have a spokesperson who is best known for using his strength inappropriately. No thank you, milk. I'll just eat my Fruity Pebbles dry from now on.

1 Brett Favre – Wrangler
Everyone enjoys a good pair of jeans. They're comfortable and incredibly versatile. However, we should never buy a pair of Wranglers thanks to Brett Favre. Based on the current camera phone photos of him floating around the Internet, it doesn't look like Favre spends much time wearing them anyway. So, how comfortable could they actually be?
