If failed corporate mergers teach us anything about business, it's that bigger is not always better.

Yep, with a 70 to 90 percent chance of dying, mergers are more likely to fail than marriages. But such daunting prospects fail to deter big corporations like American Airlines and Office Depot from attempting to defy the odds.

Check out our list of mergers that were epic failures:

  • Arby's And Wendy's

    In 2008, <a href="http://abcnews.go.com/Business/IndustryInfo/story?id=4717253">the owner of Arby's bought Wendy's for $2.34 billion</a>. Only three years later, <a href="http://dealbook.nytimes.com/2011/06/13/wendys-sells-arbys-to-private-equity-group/">Wendy's decided to sell Arby's to a private equity group</a> after the roast-beef sandwich chain <a href="http://www.forbes.com/sites/heatherstruck/2011/06/13/wendys-to-sell-arbys-in-430-million-deal-with-roark-capital/">continually struggled to grow its profits</a>.

  • Bank Of America And Countrywide

    Bank of America's acquisition of mortgage lender Countrywide in 2008 would later be <a href="http://online.wsj.com/article/SB10001424052702303561504577495332947870736.html?mod=WSJ_hps_LEFTTopStories">referred to as</a> "the worst deal in the history of American finance." The bank paid just $2.5 billion for Countrywide, a deal that ended up costing the bank more than $40 billion.

  • Kmart And Sears

    For $11 billion, <a href="http://www.nbcnews.com/id/6509683/#.USPuNuhi4gA">Kmart acquired Sears in 2005</a>. Sears' <a href="http://www.nytimes.com/2010/12/22/business/22sears.html?pagewanted=all">revenue dropped by more than 10 percent in the years following the merger</a>, according to the New York Times. Eddie Lampert, the investor in charge of the deal and CEO of Sears, <a href="http://247wallst.com/2007/12/06/herb-greenberg/">was deemed the worst CEO of the year</a> in 2007.

  • eBay And Skype

    <a href="http://www.pcworld.com/article/171267/skype_ebay_divorce_what_went_wrong.html">eBay decided to buy Skype for $2.6 billion</a> in 2005, only to sell the company four years later for $1.9 billion. Similar to the Sprint-Nextel failure, eBay and Skype were unable to successfully integrate their technological systems, according to PC World.

  • AOL And Time Warner

    In 2000, AOL announced that it was buying Time Warner for $160 billion<a href="http://news.cnet.com/2100-1023-235400.html"> to create the "world's largest media company,"</a> according to CNET. The combination didn't last long. In 2009, <a href="http://news.cnet.com/8301-1023_3-10250944-93.html">Time Warner separated entirely from AOL</a>. Jerry Levin, who sold Time Warner to AOL, later told CNBC,<a href="http://www.telegraph.co.uk/finance/businesslatestnews/6937916/The-shortlist-for-worst-takeover-of-the-century.html"> "I presided over the worst deal of the century, apparently." </a> AOL agreed to acquire The Huffington Post in February 2011.

  • Sprint And Nextel

    Deemed <a href="http://money.cnn.com/2004/12/15/news/fortune500/sprint_nextel/?iid=EL">"the merger of equals," </a>Sprint and Nextel agreed to a $36 billion deal in 2005. Technological differences between the two companies proved to be a difficult challenge and Sprint plans <a href="http://money.cnn.com/2012/05/29/technology/sprint-nextel-shutdown/index.htm">to shut down the Nextel network this June</a>, CNN Money reports.

  • Quaker And Snapple

    Quaker acquired Snapple in 1994 for $1.7 billion. Just 27 months later, <a href="http://articles.latimes.com/1997-03-28/business/fi-42931_1_quaker-bought-snapple">Quaker sold the company for $300 million</a>.

  • Daimler-Benz And Chrysler

Ultimately, Chrysler's focus on accommodating customers with lower incomes did not fit with Daimler-Benz's luxury car making business model. In 2007, Daimler-Benz paid <a href="http://www.time.com/time/specials/packages/article/0,28804,1894731_1894734_1894722,00.html">$650 million to Cerberus Capital Management </a>to sever its ties with Chrysler, according to Time.
