Super Bowl ads cost millions of dollars to conceptualize, produce, and air. The investment can be worth it, however, as it’s the one time of year audiences aren’t rolling their eyes when they must sit through a block of commercials.

While many ads are memorable for their production values, emotional punch, or laughs, some end up leaving audiences scratching their heads and wondering, “How did that get made?”

Some ads are memorable simply for being remarkable wastes of time and money.

Here’s a look at some of the worst Super Bowl ads ever:

Bud Light (2007). What’s something many people like? Beer. What’s something many people hate? Clowns. So, the question is, what good could come from combining the two? Nothing — as this ad shows. For something that airs during the Super Bowl, a time when we’re supposed to see the very best of advertising, this ad is lazy, a little crude, and just creepy.

Bud Light has certainly stepped up its advertising game since then; this spot dropped in 2007.

General Motors (2007). How did the pitch meeting for this spot go? How do you sell an ad to millions of Americans that makes light of…suicide? A robot is shown making a mistake at work — and then we slowly watch as its life spirals downward. There’s some vague point made at the end about a car warranty, but it was lost on most viewers; they were either shaking their heads in disbelief or scratching their them in confusion.

Salesgenie.com (2008). Think about this: Millions of dollars were spent on this poorly animated, poorly written, poorly thought-out spot for Sales Genie. The Asian stereotypes are cringeworthy, and overall, it boggles the mind that a company thought this represented its business.

The U.S. Census Bureau (2010). If pork spending got on your nerves before, wait until you watch this ad.

The U.S. Census Bureau decided it would be best to spend $2.5 million on a Super Bowl ad to raise awareness of the agency — and to get people to fill out their information and make things run a little smoother.

If that doesn’t infuriate you enough, the commercial is like a homemade parody of bumbling government workers too confused to do their jobs.
