Probably the one Georgiansilver posted, but just for completeness, here's the other one.

Don't Laugh At Me
June Tremayne; Norman Wisdom

I'm not good-looking, I'm not too smart
I may be foolish but I've got a heart
I love the flowers, I love the sun
But when I try to love the girls
They laugh at me and run

Don't laugh at me 'cause I'm a fool
I know it's true, yes I'm a fool
No-one seems to care
I'd give the world to share
My life with someone
Who really loves me
I see them all falling in love
But my lucky star hides up above
Someday, maybe, my star will smile on me
Don't laugh at me 'cause I'm a fool
