I Can't Stop Farting

Last night I had burritos and drank alot of beer
 And now a funny smell is eminating from my rear
 My girlfriend tries to hold her nose and falls into a swoon
 I got a problem and I don't know what to do
 HELP!
 I can't stop farting (4x)
 My flatulant [bad word] sounds like 27 ducks
 I sit and try to take a [bad word] outta luck
 My sphincter rears it's ugly head as I clear out the room
 I got a problem and I don't know what to do
 HELP!
 I can't stop farting
