Who Put The Benzedrine In Mrs. Murphy's Ovaltine?

Mrs. Murphy couldn't sleep
 Her nerves were slightly off the beat
 Until she solved her problem
 With a can of Ovaltine
 She drank a cupful most every night
 And oooo how she would dream
 Until something rough got in the stuff
 And made her neighbors scream. OW!
 Who put the Benzedrine, in Mrs. Murphy's Ovaltine?
 Sure was a shame, don't know who's to blame
 Cause the old lady didn't even get his name
 Where did she get that stuff?
 Now she just can't get enough
 It might have been the man who wasn't there
 Now Jack, that guy's a square
 She never ever wants to go to sleep
 She says that everything is solid all reet
 Now Mr. Murphy don't know what it's all about
 Cause she went and threw the old man out. Clout!
 Who put the Benzedrine, in Mrs. Murphy's Ovaltine?
 Now she wants to swing, the Highland Fling
 She says that Benzedrine's the thing that makes her spring.
 Ah, spring it now Gibson.
 This is the second you know
 The name of this is called, "Who put the Nembutals in Mr. Murphy's overalls?
 I don't know
 She bought a can of Ovaltine, most every week or so
 And she always kept an extra can on hand
 Just in case that she'd run low
 She never, never been so happy, since she left old Ireland
 'Till someone prowled her pantry, and tampered with her can. Wham!

 She stays up nights making all the rounds
 They say she lost about 69 pounds
 Now Mr. Murphy claims she's getting awful thin
 And all she says is, "Give me some skin." Mop!
