Funny Girl (from ''Funny Girl'' - The Movie) lyrics

Did you hear that?
Yeah, the guy said
"honey, you're a funny girl."
That's me
I just keep them in stitches
Doubled in half,
And though i may be all wrong for a guy,
I'm good for a laugh,
I guess it's not funny,
Life is far from sunny,
When the laugh is over
And the joke's on you,
A girl oughta have a sense of humor
That's one thing you really need for sure
When you're a funny girl
The fella said "a funny girl"
How it ain't so funny,
Funny girl
