Wow! I can't believe it! This countdown caused my sub count to skyrocket from 1700 subscribers to 2000 SUBSCRIBERS in just 10 days! At long last, this countdown is finally out! I hope I don't waste too much time slaking off when doing my next two countdowns, because I want them out by the end of May. Wow, I just hit a new record. 10000 views in a week! I can’t believe how amazed I am.
