一首耐克广告歌

一定是这首！！！
always look on the bright side of life

some things in life are bad,
they can really make you mad,
other things just make you swear and curse.
when you're chewing on life's gristle
don't grumble, give a whistle.
and this'll help things turn out for the best.
and....
always look on the bright side of life,(whistle)
always look on the bright side of life,(whistle)
if life seems jolly rotten,
there's something you've forgotten,
and that's to laugh and smile and dance and sing.
when you're feeling in the dumps,
don't be silly chumps.
just purse your lips and whistle, that's the thing.
and...
always look on the bright side of life.(whistle)
come on...
always look on the bright side of life...
for life is quite absurd,
and death's the final word,
you must always face the curtain with a bow.
forget about your sin
