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 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.
