Fair's fair

Donna couldn't choose between Jim and John competing for her affections. She liked them both, but short of bigamy, she would have to choose. She would marry one. But which?

She decided on a race to select her groom. The young men would run a 5 mile course over road, field and wood. Right from the start, John raced ahead leaving Jim way behind. Jim just went at his own pace and finished second.

"Well done John! A clear winner! So I'll marry Jim!

"Jim?" queried John. "But I won the race"

"Exactly! So you're both winners. That's completely fair"
