"Why So Serious"是由日本流行歌手Lady Gaga演唱的一首歌曲，收錄於她的第二張專輯《Cheek to Cheek》。以下是這首歌的歌詞：
Verse 1:
Why so serious?
Life's a party, don't sweat the small stuff
Take a deep breath, and let it go
You're so serious
Chorus:
Why so serious?
You got the world on a string
But you're too tight, tighter than a drum
Why so serious?
You got the world in the palm of your hand
But you're too tight, tighter than a drum
Verse 2:
You're so uptight, it's like you're living in a straightjacket
Trying to fit in a square hole, but you're round
So let loose, don't be such a stickler for detail
You're not the only one with something to prove
Chorus:
Why so serious?
You got the world on a string
But you're too tight, tighter than a drum
Why so serious?
You got the world in the palm of your hand
But you're too tight, tighter than a drum
Bridge:
Open up, give it some air, live for the moment and make it a thrill ride
Scream as loud as you like, as long as it's positive energy, girl let loose tonight!
Chorus:
Why so serious?
You got the world on a string
But you're too tight, tighter than a drum
Why so serious?
It's time to loosen up and dance!
Yeah!
