When sailors want to kill a baby seal, they have 3 ways to do it. Either shoot it in the head, hit it with a blunt object or a hakapik. They usually go for the hakapik since it's the easiest to use, but if they don't have one, they will use the blunt object (like a baseball bat or golf club). It is also used as a saying because it is an easy task if you hit the seal right in the head, similar to shooting fish in a barrel.
"When I was working on the boat, they made me club baby seals"
"We won the race with 3 minutes to spare. It was like clubbing baby seals."

Get the Club gogglesmug. An informal list of consisting mostly of popular musicians, artists, actors, and other celebrities who died at age 69. It's a play on a similar list, the 27 Club, and the notion of the number 69 being "nice."
