DNA
From TeeVeePedia, the Internet TV Encyclopedia.
DNA is an acronym that stands for a scientific term that you more than likely can't pronounce. It makes frequent guest appearances on CSI and is occasionally seen on other police procedural shows. DNA is also used on daytime talk shows to determine the identity of the father of that day's guest.
"What's DNA, anyway? Just three little letters. Probably stands for 'Did Not Attack.'" - Johnnie Cochran
