I am currently in-love with two channels in YouTube. Number one is Shanedawson ♥ And Number Two is Smosh. Both of them are like OSM~ [Shall I say Three of them? XD] No but seriously, They're funny.. XDD heartheart
Hm, I tend to pick and choose series more than I do channels. That said:
Total Biscuit and Yogscast -> their LP Magicka (if one can call them killing each other "playing" xD ) Hello, do you like bees? rofl
Yogscast -> About 90% of their videos, but especially Shadow of Israphel and some of their custom map play throughs.
Captain Sparklez -> His Skyblock survival was fun to watch. I also have him to thank for making me sing the lyrics to "TNT" and "Revenge" whenever I hear the originals ("Dynamite" and "DJ's got us falling in love again" (sp)).
I used to watch Chuggaconroy for his Pikmin play-through.
Oh, and I can't forget the best abridgers of ALL TIME: LittleKuriboh, ShadyVox, and TheAzureCrow. I will never stop watching their collaborations...or "Leather Pants". ;]
