Who would have guessed this song is really an ode to pipe smoking!

From the sheet music at Indiana University Sheet Music Collections:

SWEETHEART OF SIGMA CHI
Words, Byron D. Stokes. Music, F. Dudleigh Vernor. 1912.

1. When the world goes wrong, as it's bound to do,
    and you've broken Dan Cupid's bow,
And you long for the girl you used to love,
    the maid of the long ago,
Why, light your pipe, bid sorrow avaunt,
    blow the smoke from your altar of dreams,
And wreathe the face of your dream girl there,
    the love that is just what it seems.

CHORUS: The girl of my dreams is the sweetest girl
    of all the girls I know.
Each sweet coed, like a rainbow trail,
    fades in the afterglow.
The blue of her eyes and the gold of her hair
    are a blend of the western sky,
And the moonlight beams on the girl of my dreams.
    She's the Sweetheart of Sigma Chi.

2. Ev'ry magic breeze wafts a kiss to you
    from the lips of your "Sweet Sixteen,"
And one by one the maids you knew
    bow to your Meerschaum Queen.
As years drift by on the tides of time,
    and they all have forgotten but you,
Then the girl of your dreams the sweeter seems.
    She's the girl who is always true.
