Grigor Dimitrov fell victim to a press-room prank thanks to Ryan Harrison's innovative mind. The American hijacked the interviewer's questions, beginning with making Dimitrov think he had not qualified for the ATP Finals semifinals (he most certainly has).

Then came the awkward question, "What made you decide to go with tennis over modeling?"

Dimitrov was clearly confused, and even a bit embarrassed.

Harrison really just wanted to hear the Bulgarian sing. Despite saying "I definitely don't want to sing," Dimitrov was a great sport and belted out a bit of "I Want it That Way."

After realizing the whole debacle was a joke, Dimitrov admitted, "I was thinking these are the worst questions."
