EVERYONE SAYS I LOVE YOU
Words by Bert Kalmar, music by Harry Ruby.
As sung by Groucho Marx in "Horse Feathers" (1932)

Everyone says I love you
But just what they say it for I never knew
It's just inviting trouble for the poor sucker who
Says I love you.

Take a pair of rabbits who
Get stuck each other and begin to woo
And pretty soon you'll find a million more rabbits who
Say I love you.

When the lion gets feeling frisky and begins to roar,
There's another lion who knows just what he's roaring for.

Everything that ever grew,
The goose and the gander and the gosling too,
The duck upon the water when he feels that way too,
Says ("Quack, quack, quack.")

[It's not a ukulele; it's a guitar, and Groucho seems to be really playing it. At least he knows how to fret some chords. The blonde is Thelma Todd. The duck is fake. If I remember correctly, the song is reprised several times in the film.]
