Hey Nancy!

 NB> since I find the taste of it totally nasty

Like everything, there is beer and then there is beer.

 NB> Maybe we could use bottles of water on the wall

It seems to me the original concern wasn't about the bottled beverage but
instead the threat of 98 days of countdown where all that changes is the number
 of bottles, with only the last two days offering some variation - "1 bottle of
 beer on the wall" and "Go to the store and buy some more" on the 0 bottle day.
  Given the previous 98 days I doubt that is enough to placate anyone who would
 object being subjected to the months of daily annoyance.  I seriously doubt
that bottles of water are going to be much less objectionable to those who will
 potentionally object.

For example something like the "The 12 Days of Christmas" might be more
acceptable given it is only 12 days instead of 100 and has more variety in the
offerings per day.  Having said that I don't believe "The 12 Days of Christmas"
 is appropriate for the occasion in question but it is a very good example of a
 countdown song.

Speaking for myself, who took the time to program the routine, I am inclined to
 leave well enough alone including the bottled beer which is traditional as far
 as the original song is concerned, although I did find one reference where pop
 was an acceptable substitution.  Personally I don't agree but then again I
have no claim whatsoever for "99 Bottles of Beer".  Probably the best source of
 information is https://en.wikipedia.org/wiki/99_Bottles_of_B... especially the
 section labelled "Mathematically inspired variants".  However it still lacks
any suggestion for a reduction in duration of the potential annoyance in the
Little Mikey's Brain implimentation.

Life is good,
Maurice
