Well, let's see... both in their respective sport line up for the first shot. The golfer misses the hole by 50-75 yards. He says "Did you see that great shot!"
The pool player takes his first shot. IF he was so bad as to miss the hole by even a mere 20 yards, well, he would have his picture posted for all to see in the Hall Of Shame, he would be barred from coming within 500 yards of any pool table, he would cause laughter to ring out around the world.
The golfer gets a mulligan, the pool player gets to sit and watch his oppponent win after making an errant shot.
The golfer gets usually about 36 shots to put 9 balls in the hole, the pool player usually gets only 9 shots to do so.
The golfer needs a caddy to tell him what club to shoot with, how to hit it, ect. The poolplayer gets no one to coach him. He has to be smart enough to figure out what to do on his own.
