In this particular universe (the one you live in if you're reading this), Rhett and Link are lifelong best friends who met in first grade and host a popular Internet show. But in a parallel universe (which just so happens to be the universe of Rhett & Link's Buddy System: Another Dimension), that meeting never happened. Instead, they meet as adults, and Rhett is a self-absorbed hedonist while Link is alarmingly simple. Will they each be able to grow enough to form the “buddy system” their counterparts enjoy in this universe?
