"Last Friday Night (T.G.I.F.)" 是由 Katy Perry 演唱的一首歌曲。以下是這首歌的歌詞：
Last Friday night, I said yeah yeah yeah
Last Friday night, I said yeah yeah yeah
Last Friday night, I danced till 2, 2, 2
To the radio, the DJ played my favorite tune
Drinking vodka, doing shots, feeling no pain
Drinking vodka, doing shots, oh what a night
Oh what a weekend
Tonight's the night
Get up feeling high
On Sunday morning hangover too
Yeah
Last Friday night we said yeah yeah yeah
Yeah, what a way to say goodbye
To the week, goodbye
We stayed up laughing till the sun came up
All day Sunday, sleeping with the one I love
Oh what a weekend
Tonight's the night
Get up feeling high
On Sunday morning hangover too
Yeah
Last Friday night we said yeah yeah yeah
Yeah, what a way to say goodbye
To the week, goodbye
Last Friday night, I said yeah yeah yeah
Last Friday night, I said yeah yeah yeah
Yeah, it was a crazy night
And I ain't lying when I say it was wild
Everybody in the club was feeling alright
And now we're up sipping on some more coffee today
Yeah
Last Friday night we said yeah yeah yeah
Yeah, what a way to say goodbye
To the week, goodbye
Yeah, last Friday night... yeah yeah yeah...
Yeah, last Friday night... yeah yeah yeah... yeah...
