Think once is enough to say "I do?"  Not so for a couple in Tennessee who've set the Guinness World Record for "Most Marriage Vow Renewals by the Same Couple." 

Lauren and David Blair of Henderson, TN  have renewed their wedding vows 99 times  since tying the knot in 1984.  Lauren told reporters that she knew she and David were meant for each other and she loves looking in David's eyes as he repeats his wedding vows.  Every time the couple renews their vows, they pick a different location for the ceremony.  They most recently renewed their wedding vows, for the 99th time, this past Sunday in Honolulu, Hawaii.  Cool or kind of tacky to keep renewing your vows so many times?
