IN HONOR OF [R, S, T, & U]

She’s a quick study
Whose Understudy
Understands: She
Needs not Study
Or Overstudy,
Study Steadily,
Or Study Readily,
She’s always Ready,
She Studies Steadily,
And studies Regularly,
UnTil You’re Ready
Really ready
To go steady
If Still not ready?
To go steady?
She won’t sweat it;
Won’t regret it.
She’ll just Discredit
With Your Understudy.
