Educate yourself, dork:
A gauntlet is “a heavy glove, often armored” or “a glove with a heavy cuff covering part of the arm.” To throw down the gauntlet is to challenge someone; to pick up the gauntlet is to accept someone’s challenge.
A gantlet is “a lane between two lines of people armed with staves or whips, through which someone being punished is forced to run while being clubbed or whipped by the people on either side” (run the gantlet) and, figuratively, “any series of trials and difficulties.”
To complicate matters, each is a variant spelling of the other. If you look up the words in a dictionary, most will say they're variants of one another. But there is a historical distinction.
