From Oh, the Places You'll Go!, I'll pass on this bit of mulish advice:
"Be sure when you step.
Step with care and great tact
and remember that life's
a great balancing act.
Just never forget to be dexterous and deft
And never mix up your right foot with your left.
And will you succeed?
Yes! You will, indeed!
(98 and 3/4 percent guaranteed.)"
Does that sound like a mule navigating a treacherous spot, or what? I have a feeling that the honorable doctor might have known a longear or two in his time.
