Not sure if we should blame this fail on Subway or Michael Phelps. TMZ reports that the reps for Subway said

“It’s just an unfortunate coincidence, adding the Fresh Buzz site has been around for 3 years.”

Regardless of what was intended I think they knew exactly what people would think. After all, it got my attention and reminded us all that Michael Phelps love the Ganja. It’s ok if your munchie craving leads you to Subway, It’s healthier than McDonald’s and all natural just like Marijuana.
