Sure you do. All through November. There was No Shader November, and: Blue boots Wednesday (first Wednesday in November) to raise awareness of HIV in Goats. Chatterwhite Tuesday (second Tuesday of November, the only day in November when you can wear a shader) To raise awareness of the plight of the Czechoslovakian swamp frog. All exotics Friday (First or last Friday of November, depending on the moon's orbit) where you get to have exotics in every slot; To raise awareness of the injustice suffered by the children of middle class suburbanites. No Warlock Wednesday, No Hunter Thursday and No Titan Saturday (All held in the 3rd week of November) To raise awareness of the struggles suffered by the Daffodils that accidentally, and through no fault of their own, find themselves growing in a field full of Pansies. Naked Sunday (Last Sunday of Month), Guardians do all activities without armour and can equip only a throwing knife. To highlight the injustice perpetrated by Spiders, holding fly's without trial or reason, only to then eat them (Please give generously to this charity, they doing some good work). You don't remember any of this stuff in November dude? It's always been a thing. 'Wacky November' me and my fire-team call it. As soon as calendar hits November 1st it's like "What's it going to be like on naked Sunday this year?" Oh the fun we have in November. You really don't remember?
