Other boxers are famous for their patented punches, jabs, straights or hooks but Manny Pacquiao best them all with not a punch but with 2 simultaneous punches.  The Pinoy champ entertained everyone when he pulled out a trick from his sleeve.  Foreigners may not be familiar with it but Filipinos am sure are.  Ancient action stars like Fernando Poe Jr and Lito Lapid do it all the time.  "Pompyang" that's what we call it, taken from the brass cymbals used in "drum and bugle" bands.  The fight with Joshua Clottey was so lopsided and surely that moment in round number 4 was the most eventful of the fight.  I was laughing may arse out of the sofa.  hahahaha.

Apparently, MP does it all the time....See excerpts from Sweet Science:

[Pacquiao drew] a stern admonition from referee Rafael Ramos when he slammed his fists against both of Clottey’s ears at once. Roach chalks that one up to, well, a case of Manny being Manny.


“He does it in a gym all the time,” said Roach. “I don’t think there’s been a guy he ever sparred with he didn’t try it on, and Steve Forbes, in this camp, was the first guy who’d even retaliated. When he talked about doing it in a fight I warned him ‘Manny, don’t even think about it, because they’ll take a point away if you do.’”
“No they won’t,” replied Pacquiao. “The first time I do it they’ll just warn me.”

In gym sparring, or in amateur bouts, the technique can be downright dangerous, since catching an opponent wearing tight-fitting headgear on both ear-holes at once could easily rupture an eardrum, “but I frankly don’t understand why it should be illegal in a professional fight,” said Roach. “I’ve asked a bunch of people and never gotten a good answer. Think about it: all you’re doing is throwing two punches at the same time. I can’t think of any rule that says you can’t do that".

I know that Manny's previous movies were all flops but he can make them work by giving out more "pompyangs".
