No sources, no evidence of notability. Oren0 (talk) 06:50, 5 February 2008 (UTC)
 * Weak Delete I did a quick Google and didn't really see anything so I agree with nom, reason for weak is cause I gladly admit I skimmed the Google results so I could have missed something. --Sin Harvest (talk) 10:38, 5 February 2008 (UTC)
 * You did. They're called books.  This puzzle has been discussed in books on mathematics written by authors such as Martin Gardner, Ravi Vakil, James Roy Newman, Albert Geoffrey Howson, Jean-Pierre Kahane, Brian Clegg, Paul Birch, Charles Stanley Ogilvy, and Edward De Bono, amongst others.  There's one book, by I. Grattan-Guinness and Roger Cooke, that tells us that this was one of Lewis Carroll's favourite brainteasers.  This problem is also in Grolier's Encyclopedia International.  "No sources" is the claim here?  Pull the other one!  It's got bells on.  Jonathan de Boyne Pollard (talk) 12:51, 5 February 2008 (UTC)
 * If there are sources, please cite them. There are a million popular riddles, I don't think each one merits a wikipedia article with no info other than the problem and its solution.  Perhaps the article should talk about the history, why it's relevant or interesting mathematically, etc.  All I see right now is a riddle and answer, which itself don't constitute encyclopedic information in my opinion.

 * I did say it was a weak one for a reason didn't I? Well if you've got the sources put them in and add in the Lewis Carroll thing as well it will add to the article. --Sin Harvest (talk) 10:30, 6 February 2008 (UTC)
 * Delete per nom. RogueNinja talk  11:10, 5 February 2008 (UTC)
 * Weak keep I'm sure sources for this could be found. User:Jonathan de Boyne Pollard gave some useful leads on sources. The article certainly doesn't claim notability, but I don't think it would be difficult to include such notice. --Rkitko (talk) 13:12, 5 February 2008 (UTC)
 * Delete Unless notability is demonmstrated. Paul August &#9742; 02:56, 6 February 2008 (UTC) Keep Changed my mind based on additional referencing. Paul August &#9742; 01:38, 7 February 2008 (UTC)
 * Keep I personally came across this puzzle for the first time in the spring of 1985.  It was given by some invited speaker in a problem-solving and creativity seminar at IBM, Austin, Texas.  My mentor, who was in the seminar, showed it to me afterwards.  I solved it in a few seconds, and showed him the logical steps on a whiteboard. He told me no one solved it in the seminar.  It was called something like "Coke and Pepsi puzzle" at that time. Giftlite (talk) 16:16, 6 February 2008 (UTC)
 * Strong keep. Well-known problem; also, article is sourced. Spacepotato (talk) 00:16, 7 February 2008 (UTC)
 * Keep although I have also heard this problem by a different name. -- Nick Penguin ( contribs ) 00:36, 7 February 2008 (UTC)
 * Keep - notable problem; article now well sourced (good job, Spacepotato). Gandalf61 (talk) 16:23, 7 February 2008 (UTC)
 * Keep A standard bit of folklore. Michael Hardy (talk) 23:35, 7 February 2008 (UTC)
 * Keep. As the other comments above already state, this is a very standard problem, and is now appropriately sourced. —David Eppstein (talk) 03:28, 8 February 2008 (UTC)
 * Keep per the comments above. John254 01:15, 10 February 2008 (UTC)
