Shortly after his liaison with the taco stand lady, Joe makes a horrible discovery...

Joe:
Why does it hurt when I pee?
Why does it hurt when I pee?
I don't want no doctor
To stick no needle in me
Why does it hurt when I pee?
I got it from the toilet seat
I got it from the toilet seat
It jumped right up
'N' grabbed my meat
Got it from the toilet seat
My balls feel like a pair of maracas
My balls feel like a pair of maracas
Oh God I probably got the
Gon-o-ka-ka-khackus!
My balls feel like a pair of maracas
Ai-ee-ai-ee-ahhhh!
Why does it
Why does it
Why does it
Why does it hurt when I
Peeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee?
