New twist on ol song:
"Happy Birfday to yo" (Point imginary pistols or guns at each guest and go BOOM BOOM)
Repeat after swig from yo .40 oz
"Happy Bifday to yo" (BOOM BOOM shuffle end zone dance)
"Happy bifday, Happy bifday", "Happy bifday to yo" (Every body chases each other with an imaginary AK or Glock .fotay)
No need for second chorus of "You look like a Monkey and live near the ZOO"!
everybody knows that, Mr. Obvious
Now we cut the crack, blow out a fart, and play pin the condom on Homey.
I doubt that was the song my friend was singing, but your point is conveyed and noted.
