So I twittered the other day, while watching Saturday Night Live, that the McGrubber segment should just stop. It’s never been funny, and adding McGuyver and Pepsi, all at once, hasn’t helped. Actually, I Twittered. Capital T to indicate the use of the Twitter social posting service that is gaining on pretty much everything. Turns out that when you Twitter, people listen. People you don’t know. The next morning I was notified that “Pepsuber” was following my Twitter feed. Who is Pepsuber? Well, it seems that McGrubber is sponsored by Pepsi, and the actor is Twitting away under this new name. To people who complained or mentioned McGrubber on Twitter. He was suddenly following over 900 people that morning. By “he,” I really mean some Pepsi marketing intern, I’m sure. There are a number of genuine celebrities on Twitter, but since this smacks you every which way with “marketing campaign”, I’m thinking interns.
