Party Tonight

Party Tonight is the song Mordecai and Rigby perform in the episode Mordecai and the Rigbys. Unfortunately, they realize that they have been tricked into lip-syncing the entire song.

Lyrics
Your eyes staring into my eyes,

Who am I but a guy with two eyes on the prize,

And the prize in my eyes is 10 times,

The surprise in your eyes as I kiss you goodnight.

''Your smile is the fire that rocks my soul gonna remember it until I grow old,''

'Cause life is too short we gotta do things right, ''

So baby let's just party﻿ to-night-''

Baby let's just party﻿ to-night. ''

We've come out on top, We're in front of the line,''

We're here to rock out and have a good time,

'Cause the past is the past and the future is bright,

So baby let's just party﻿ to-night,

Baby let's just party﻿ to-night.
