Floyd Mayweather Jr. certainly knows how to make the most of social media. He doesn't just post random tweets of betting slips; he knows how to use 140 characters to stir things up.
One day, he's proclaiming that he's likely to fight Devon Alexander on May 4, despite all the evidence to the contrary. Then, yesterday he tweeted: "Me & my trainer (my dad) back working together getting ready for May 4th." To prove the point, there was a photograph of the two standing together, a scene that seemed improbable at best after their bust-up in the gym in front of HBO's cameras on "24/7" in August 2011.
The notion that the two Floyds might reunite in the corner had been mooted recently (even as Roger Mayweather -- senior's brother and, in recent years, junior's trainer -- struggles with health issues). So this is another twist in the ongoing saga of their personal and professional relationship. Of course, they are far from the only notable father-and-son corner team in boxing, and like parental-filial relationships elsewhere, they run the gamut. Here is a short selection of some of the more colorful, sometimes successful and sometimes painful case studies:
1. Roy Jones Jr. and Roy Jones Sr.
At times, the apparent dysfunction between these two has been enough to make Floyd Sr. and Jr. look like Bill Cosby and Malcolm-Jamal Warner (kids, ask your parents). On the plus side, Big Roy did teach his son how to box; against that, he also shot his boy's favorite dog. After years of personal and professional estrangement, Jones invited his father to work in his corner for the third fight against Antonio Tarver. When Jones lost that bout by a wide margin, he essentially said he didn't try to win because he didn't want his father to take the credit.
2. Nonito Donaire Jr. and Nonito Donaire Sr.
Donaire pere trained Donaire fils until an incident during training for the son's November 2008 fight with Moruti Mthalane led to the end of their professional relationship. Despite occasional talk of reconciliation, the father-son personal relationship, too, has become strained, at times very publicly so.
3. Danny Garcia and Angel Garcia
There doesn't appear to be any strain between Angel and junior welterweight titlist Danny. If anything, Angel's love for Danny at times verges on the overwhelming, as his extreme defensiveness of his son leads to intense verbal confrontations with Danny's opponents, including Amir Khan and most recently Zab Judah.
4. Shane Mosley and Jack Mosley
It's easy to forget now, but in 1998 Jack and Shane Mosley became the first ever father-son tandem to receive trainer of the year and fighter of the year honors from the Boxing Writers Association of America. But after losses to Vernon Forrest and Winky Wright, Jack and Shane -- who remained close personally -- broke up professionally before reuniting and breaking up again. They were slated for another reunion if Shane's putative bout with Paulie Malignaggi had taken place as planned this month.
5. Joe Calzaghe and Enzo Calzaghe
An unalloyed success: Enzo steered Joe to world titles at super middleweight and light heavyweight. And after Joe retired with an undefeated record, he and Enzo then formed a promotional partnership. Although Joe had well-documented personal troubles in his immediate post-retirement years, his relationship with his father has evidently remained strong.
