This
shy fellow may clam up upon occasion, but you can coax him out of his shell.
Just put your thumb in his lower half, middle finger in his top half, and ring
and index finger in his eye stalks. It's an open and shut case!
I use these fellows as back up singers for "The Best Tunes
Under the Sea." At this price you can order a quartet or a choir.
"Don't Clam Up" is a great catch phrase for these guys to
teach your class the importance of sharing their faith with others instead of
claming up.
