Friends Season 2 Episode 6

Phoebe's Songs: "Shower Song"
I'm in the shower and I'm writing a song
Stop me if you've heard it.
My skin is soapy, and my hair is wet,
and Tegrin spelled backward is Nirget.
Lather, rinse, repeat
and lather, rinse, repeat
and lather, rinse, repeat
as needed.

"I Play For Me"
When I play, I play for me
I don't need your charity
La lalala lalalalalalala
lalala lalala lalalalalalala....

"Double-Jointed Boy"
...was the double, double, double-jointed boy.

"Stephanie"
Stephanie knows all the chords.

"Terry"
Terry's a jerk!
And he won't let me work!
And I hate Central Perk!
You're all invited to bite me!

"Smelly Cat"
Smelly Cat, Smelly Cat,
What are they feeding you?
Smelly Cat, Smelly Cat,
It's not your fault.
