Dave, Ben, Duncan, and Jonnie have created a bucket list, and their quest to fill it unfolds on this series, which follows the young men -- all in their 20s -- traveling across North America in a purple bus on a mission to change lives, spread hope and make dreams come true. The list of 100 things they'd like to do before they die includes: kiss actress Megan Fox, play basketball with President Obama, camp at the Playboy Mansion, and host "Saturday Night Live." Each time they fulfill an item, they help one stranger achieve a dream of his or her own.
