Relay runners hand each other a baton. “You’ve got to hand it to Relay Teams #win100” is a pun that was posted on Twitter by Alan Machnik on November 1, 2010. Machnik also posted the joke on Twitter on May 30, 2012, and again on Twitter on June 6, 2014.
   
 
Wikipedia: Relay race
A relay race is a racing competition where members of a team take turns completing parts of racecourse or performing a certain action. Relay races take the form of professional races and amateur games. Relay races are common in running, orienteering, swimming, cross-country skiing, biathlon, or ice skating (usually with a baton in the fist). In the Olympic Games, there are several types of relay races that are part of track and field.
