Six Flags Great Adventure Safari Warden Mike Miller is on a mission!

He's hoping to break a Guinness World Record in March...but it has nothing to do with animals.

Miller is putting his vocal cords to the test, hoping to secure the record for longest karaoke marathon. His goal is 107 hours -- that's a little over 4 days!

Why do this, you ask? He says, 'I’ve had two dreams in life – to work with animals, and to break a world record. I work with some of the most amazing animals in the world at Six Flags, so now it’s time to achieve my second dream.'

The 25-year-old is doing this for a good cause too, hoping to raise $5,000 for the Wounded Warrior Project. You can donate to Miller's campaign by clicking HERE.

His attempt will begin on March 24 at McGinn's Pub in Jackson, with about 175 songs that he'll sing in a loop.

Considering that just staying awake for 4 days is probably not the healthiest idea, there will be 'safety professionals' and other volunteers on hand for the task.

Miller says,'It will take me two to four weeks to physically recover from this challenge.'

As for what he'll sing? He's partial to country music, but says, 'you’ll also hear some Def Leppard, Goo Goo Dolls and Journey, too.'

May I suggest 'The Lion Sleeps Tonight'?
