Michael Phelps gets perfect nickname at coffee shop

Michael Phelps and Nicole Johns

Olympic swim great Michael Phelps got a rather sweet surprise when he visited a Starbucks coffee shop with his wife Nicole Johnson and a friend. Interestingly, it was not about the coffee, but what was written on the cups that caught his attention. Phelps' cup had the words 'The GOAT' written on it, while his wife's read, 'GOAT's Wife,' and the third cup had, 'Friend of GOAT' scribbled on it.

Goat is an abbreviation for 'Greatest Of All Time'. Phelps posted a picture of the three cups on Twitter and captioned it: "Interesting names on our Starbucks cups today. made us all laugh #hiltonvillage."
