The two guys on the bikes are both members on the same biking team at a well known university.  They are in first and second place, leading third by a long ways.  They are coming up to the finish, and know they will come in first and second.  They are both about to graduate.  They both want to win, but they don't want to beat their teammate.  They are saying, "go ahead, take it," to each other, but they end up crossing at the same time and everybody wins.
