I removed the prod tag because I'm not convinced this is an obvious deletion. In effect, this is a disambiguation page for popular uses of pi; some people would navigate between them with a cat (which has not yet been divided from Category:Pi), but we encourage multiple means of navigation.
- Err… "disambiguation page"? This is an orphaned article. No other articles link to it. (Other than the list of mathematical stuff.) The first paragraph mentions an obscure "school cheer of MIT", with a dead link to Wikiquote. The second paragraph covers just pi day. The third covers pi time, which is, needless to say, rather obscure as well. As for the 2143/22 approximation, this can be explained by the fact that the fifth continued fraction convergent has a large denominator, and is mentioned in Mathematical coincidence and Numerical approximations of π#Miscellaneous approximations. I suppose trimming would make the situation worse (this article is pretty empty to start with), but merging or expanding are fine alternatives. CHL (aka yse) (talk) 11:14, 9 March 2009 (UTC)
