There must be a commentator training class they attend that stresses they don't ever think about what they're going to say before they say it.
"For those of you that don't know, the balls are played in numerical sequence, with the 9 being last."
"He's probably going to play the one in the corner, since it's hanging there in the pocket."
"The long stick he has is called the mechanical bridge.
"He has the cue ball on a string."
"Last time he played this guy was in Glumpville, Indiana at the Fugimar Farquar 9 Ball Memorial Open and it went hill-hill in a race to two."
"This guy's the best one pocket player in the World right now, and Efren gives him weight."
"The cue ball caught the titty on the side pocket. Those titties stick out there quite a bit."
"He normally plays with a 77" cue and screws on a 36" extension if he has to. That's why they call him Mister 113, not because he ran 113 balls." "Because of that cue, he almost got kicked off the plane and labeled a terrorist." "They were afraid he would poke the pilot from a second class seat."
"This player here is from Great Britain and he speaks and cusses in his native tongue using English."
"Nothing like a good referee turning pro. He can use all the rules to his advantage."
"This guy is the House Man in a one table pool room."
"When he's not playing pool, he's picking locks on his lock-smithing job, a skill he learned when he was incarcerated." "Say, you locked my Szamboti in your trunk didn't you?"
