Not having a sense of humor
Is nothing to laugh about

You have to push it out
Like an overdue bowel movement

Guarding your personality
Like it's something special

If you can't take a joke
It's no laughing matter

It's easier to admit your faults
Than it is to change them

If you can't laugh at yourself
Someone will do it for you

You've got to have guts
If you're  going to eat haggis

It's either I'm not funny
Or you don't have a sense of humor

I can't tell which one is the case
So you'll have to take your pick
