If the cap fits...
Things suddenly just got a lot more hectic in the Kelli White household.
Prior to this doping scandal, her private life wasn't the most exciting thing in the world.
Her boyfriend, German javelin hero Boris Henry, is such a thrill-seeker that he spends his spare time collecting caps.
Henry only occasionally exposes his head to the elements
Henry's hat obsession began on his 21st birthday, when he was given a baseball cap as a present.
Since then he has amassed a stash of hundreds, wearing as he does a fresh one for every competition he takes part in.
Like a true German, he wears them back to front, with the peak pointing down his neck.
And his nickname? "Mann mit der Mutze", which translates as the devastatingly cool "man in the cap".
Long jump joy
Don't be too hard on Jade Johnson.
Her fourth place in Saturday night's long jump final represented an excellent result - particularly when you learn that she is allergic to sand.
You heard right - a woman who leaps into a pit of sand for a living is allergic to the stuff.
It must rate as one of the most unfortunate medical conditions in sporting history, at least until we come across the swimmer who is allergic to water.
Even more hurtful for Johnson was the name of the person who out-jumped her for bronze.
The Briton was beaten by a plus-6.60m jump from none other than... Bobby George.
No, the saggy-gutted darts legend has not made a dramatic career switch from oche to runway.
India's Anju Bobby George simply has an unusual name. Okay?
X marks the spot
Do not be surprised if, in the middle of the women's high jump final, you suddenly see Russia's Marina Kuptsova taking out a protractor and sheet of graph paper.
Kuptsova gets a little help from her father
Her father and coach Gennadiy is an accomplished mathematician and prepares mathematical models for his daughter detailing precisely how a jump should be performed.
As someone whose only attempts at the high jump at school involved the now-discredited "Superman" dive, I take my hat off to her.
Champagne salesmen across Paris shed a tear when Ethiopia's Gezehegne Abera dropped out of Saturday's men's marathon just after halfway.
Had the Olympic champion successfully defended his world title, the city could have expected a party like no other.
Abera is not a man who believes in low-key celebrations. At his wedding in Addis Ababa earlier this year he had an estimated 25,000 guests.
Now that's one big buffet.
