I really hope they will try to cast some unique teams this time. Here are some ideas...
xxx LGBT team like (young) lesbian couple, transgender(s), drag queens
xxx teams with both members 50 + old
xxx overweight/obese team
xxx FF with some badass jobs like wrestlers
xxx religious team like pastors, nuns, muslims, orthodox jews
xxx "in law" team
xxx hot parent child team
xxx older parent child team (child in their 40s)
xxx parent & adopted child
xxx MF friends where no one is gay
xxx MF couple with bigger age difference
xxx MF twins
xxx roommates
xxx aboriginal team
xxx teenegers
xxx neigbors
