Hamlet: "Crouch we here awhile, and mark." – This is one of those very useful lines for if you ever forget your lines in a Ye Olde Englishe play... As one of the characters from In The Bleak Midwinter describes it, it provides a moment of tension, bit of intrigue, and a useful pause while you recollect where you're supposed to be...! Shame it eluded me on the opening night when I dried! :-P
