I too found him annoying, but watching Pitchmen and this thing on As Seen on TV on MSNBC(I think?) where he talked about his yelling, he stated "If I go 'hi Billy Mays here to sell.....' it just doesn't get their attention, but if I'm like 'HI BILLY MAYS HERE TO SELL!!!!..' it just seems to just grab your attention." I'm sure I got the words wrong, but the idea is right, and he IS right about what he said. They also talked about he's the new Ron Popeil. I really liked his personality on Pitchmen sort of a no BS, this is how it is and how it's going to be attitude. That guy knew what he was doing. I especially loved how he got ticked at that Sullivan dude and said he was going to kick his a** LMAO!!!
I'll miss that guy. RIP Billie.
