5:47 "When I didn't set the traps, the young and stupid rats took the bait, and after a while, the smarter rats, the old rats, after seeing it was safe, would take the bait as well. So after feeding them night after night, they became very comfortable wich climbing over the traps to get the food, And then one night, I pulled the swicharoo and caught ten rats! I set it up the next night, and got ten more."
