I had a little duckling (* Jumper1 starts *) Named Tiny Tim. Put him in the bathtub. Teach him how to swim.
Swallowed a bubble. Called the doctor. Called the nurse. Called the lady With the big fat purse.
In came the doctor. (* Jumper2 enters *) In came the nurse. (* Jumper3 enters *) In came the lady (* Jumper4 enters *) With the big fat purse.
Out went the doctor. (* Jumper2 exits *) Out went the nurse. (* Jumper3 exits *) Out went the lady (* Jumper4 exits *) With the big fat purse.
