PlanetNeedsHumor PlanetNeedsHumor

My planet sent me, via portal, to investigate what is funny these days. For over 700 years, my people were forbidden to LAUGH or say ANYTHING funny. By virtue of an intergalactic war, a badass new regime has come along and allowed us to laugh again! Hell yeah! Problem is, we're clueless. We forgot what was/is funny. Please Help me Help my people!
