T-Rex: Biathlon is the sport that combines SKIING with SHOOTING!
T-Rex: Love it.
T-Rex: And TRIathlon combines running, swimming, and cycling! PERFECT!
T-Rex: However that is where *I* stopped paying attention, which means I'm COMPLETELY free to invent my own, likely SUPERIOR sports as we proceed through the number system! For example, I hereby declare a QUADrathlon to be everything in a triathlon, PLUS shooting!
Utahraptor: Quintathlon?
T-Rex: Add skiing.
T-Rex: Sexathlon adds skydiving. Septathlon adds dressage, octathlon karate, nonathlon skateboarding, decathlon freestyle wrestling, and going to a vigintathlon adds weightlifting, water polo, tennis, hockey, fencing, sailing, beach volleyball, badminton, basketball, and whitewater rafting.
T-Rex: "Who could possibly excel at all twenty of these sports at once?" you ask, as if you somehow DON'T want to discover the world's newest AND most electrifying name in sports entertainment??
