"Morgan, please, put a sock on it, won't you?"
Succint and to the point. Why anyone in the cast would say anything else to him I don't know.
Looking back to those halcyon days of two years ago, I think I probably thought it was "Morgan,
please, stick a sock in it, won't you?" That's what I
always want Morgan to do. Besides, putting a sock on "it" just draws more attention to "it"...
