Shaquille O'Neal as a Jockey for Vitamin Water. Ugh. Too involved, too loud, too busy, and too long. The only laugh comes at the last second when a giant horse hoof stomps in by the logo, with TRY IT! Apparently, Shaq was pretty confident that this ad would be a hit: I put my house on the line that people are going to remember a 321-pound basketball player riding a horse. Rohan Oza, Glaceau's senior vice president of marketing agrees: It's the right thing to do...it's what people are drinking today. Not right enough, Rohan.
