A better one for a speech-impedimented audience is .... forgotten the name, but it goes
Thuthie, Thuthie, be my little thweet-heart, Thuthie,
You lithp, and I lithp, but your lithp ith worth than my lithp!
Thuthie, Thuthie, I'l pay the theven and thicth for you,
Then the parthon will whithper "Mithter Thammy Thimpson lihtpth,
And Mitheth Thuthie Thimpthon lithpth too!"


Or how about
K-k-k-katy, beautiful Katy, your'e the only g-g-g-girl that I adore ...

The Stuttering Lovers is pretty tame after these!
