Nothing dirty (apart from where they live), just clam.
This one is different from that old prozac-driven ramble, I’m serious this time.
Say it a few times with me: clam. Clam. Clam. Clam.
Close your eyes and say it slowly to yourself a few times. Clam. Now say Clip.
I think Clip sounds better after saying Clam a few times. Clop never sounds good though. Weird huh?
