One of the funniest things I found when I (as a Windows user) leant Ubuntu was that there is a command
fortune, which prints a random/pseudorandom message from a database of quotations. It is said that this old feature has been available since 1970s. It was a pity that this feature was unavailable in boring Windows OS, until the R community developed in 2012 a package called 'fortunes,' which displays funny messages taken from the talks or communications in the R community. It supports external database as well. Unfortunately, it does not support Chinese texts, probably because (1) the 'fortunes' package cannot read multibyte characters such as Chinese, and (2) no one contributes Chinese database of fortunes.
It is a great loss, as fortunes actually come from Chinese restaurants.
