Mysterious things can happen anywhere. Take this story for example. United States president Donald J Trump was spotted walking round the White House rose garden, but a few minutes later he was gone, and the only person sighted was someone resembling the Incredible Hulk.
Speculation has begun that President Trump just might be the famous green dude in his more unusual moments. Pundits suggest that Trump, consumed by recent events, has been undergoing a seismic shift in his moods, and the effect that had was to cause the President to channel the barrel-chested comic legend.
The outgoing president is under pressure to explain this anomaly, but no one expects that "The Donald" will enlighten us any further on the issue.
