“Absence makes the heart grow fonder” is an old proverb. There have been many jocular variations with “absinthe” (instead of “absence”) and “fart” (instead of “heart”).
 
“Absinthe makes the fart go ponder” was printed in a 1990 book. “Everyone knows that absinthe makes the fart go HONDA!” was cited in 1992. “Absinthe makes the fart go yonder” was cited in 1994. “Absinthe makes the fart grow louder” was also cited in 1994. “Absinthe makes the fart grow stronger” was cited in 1999.
   
“Absinthe makes the heart grow fonder,” “Abstinence makes the church grow fondlers” and “Doctor, why do I toot like a motorcycle?”/“Because abscess makes the fart go Honda” are other variations on the proverb.

Warning, BAD motorcycle joke follows…...
 
A fellow goes into his doctors office one day, and tells the doctor that he’s got to help him.  The doctor asks what the problem is.  The fellow tells him that every time he passes gas, it goes “... HONDA..”.  He says, “Its real embarrasing, cause I ride a Harley”  The doctor asks him is he consumes absinthe.  The fellow, astonished, says yes.  The doctor tells him not to use absinthe for 2 weeks then come back to see him.  Time passes (about 2
weeks) and the fellow goes back to the doctor.  The doctor asks him if his problem is cured.  The fellow says, Yes, I can’t believe it.  What did the absinthe have to do with it?  The doctor says, “Everyone knows that absinthe makes the fart go HONDA!”

Absinthe makes the fart grow Honda. I read this in the Gents of a bar heavily used by journalists, so it’s probably true.
