This improv game (created by me) is called Not funny.
You form two opposing lines facing each other so that everyone is facing someone directly in front of them. First to last is in order from right to left end of line . The First person says "you know what's funny" and tells a joke . Line reacts. Second person says " not funny"......tells joke.... that's what's funny or now that's funny
Who ever gets the most laughs wins
Process of elimination, those with least laughed at jokes are out.
Great practice for quick witted humor
