# l = '''Have A Good Time - Paul Simon
# Yesterday it was my birthday
# I hung one more year on the line
# I should be depressed
# My life's a mess
# But I'm having a good time
# Oo I've been loving and loving and loving
# I'm exhausted from loving so well
# I should go to bed
# But a voice in my head
# Says "Ah what the hell"
# Have a good time
# Have a good time
# Have a good time
# Have a good time
# Paranoia strikes deep in the heartland
# But I think it's all overdone
# Exaggerating this and exaggerating that
# They don't have no fun
# I don't believe what I read in the papers
# They're just out to capture my dime
# I ain't worrying
# And I ain't scurrying;
# I'm having a good time
# Have a good time
# Have a good time
# Have a good time
# Have a good time
# Maybe I'm laughing my way to disaster
# Maybe my race has been run
# Maybe I'm blind to the fate of mankind
# But what can be done
# So God bless the goods we was given
# And God bless the U S of A
# And God bless our standard of living
# Let's keep it that way
# And we'll all have a good time
# Have a good time
# Have a good time
# Have a good time
# Have a good time
