From the sheet music at Baylor University:


WE’VE GOT THE MUMPS
Words by Willis N. Bugbee, music by Thomas B. Weaver, ©1920.

1. ^[1]Oh, howdy, folks; excuse our looks; we’re going to sing for you.
^[2]We can’t back out; it’s been announced, so we will brave it through.
This morning when we ^[3]all took sick and sent for Doctor Bumps,
He ^[4]took a squint at us and said, “^[5]Those kids have got the mumps.”

CHORUS: Oh, yes, ^[6]we’ve got the mumps all right, ^[7]the worstest kind of mumps,
^[8]And if you don’t keep shy of us, you certainly are chumps,
For if you don’t, you’ll get exposed; that’s what the doctor said,
And it’s not any fun, you bet, to have a ^[9]swelled-up head,
To have a swelled-up head.

2. ^[10]We dasn’t go outdoors to play till we get well again.
^[11]We dasn’t eat sour pickles ’cause they give us such a pain,
And ^[12]if we laugh or cough or sneeze, it hurts these horrid lumps.
It ^[13]isn’t any funny thing when folks has got the mumps.

3. ^[14]Last year we had the whooping cough and my! how we did whoop!
^[15]The year before, ’twas measles and another time, ’twas croup;
And ^[16]once we had the chickenpox; oh, ^[17]we were in the dumps!
We’ve had most all complaints, you see, and now we’ve got the mumps.
