It's all really hilarious and self created drama.
I was on his site before I saw this video and as i was browsing around most tubes are shown as out of stock. So I well imagine people looking for tubes actually started calling to see what was available...I mean after all that is what he does...sell tubes.......

I found this fairly persuasive. Of course, freaking out is not really a good plan about anything.
