See Bash in toolforge for the current index of quips.
Quips are small quotes taken from IRC, bug reports, code reviews and other sources, that were hosted originally in our bugzilla installation (a random quip appeared at the top of the page), but with the migration to phabricator, since phabricator didn't had support for them (T73245), they were moved to toolforge.
Most quips were added by MediaWiki developers and many of them need to be put in that context. Unless you're familiar with MediaWiki development and participate in the communication channels, you probably won't understand or find them funny. ;-)
