BOXING TRIVIA PART 1000?

I know there's been a bunch of these, but I like them a lot so this is part 1001.

If I even suspect someone googled an answer, I'll go Godfather Part I on you, trap you in a toll booth, and murder you w/ a machine gun like James Caan

Here we go:

1: Which ATG fighters real name is Sergio Eligio Sardinas Montalvo?

2: Ali nicknamed this fighter "The Washer Woman" during the lead-up to both their fights.

3: Who was the first man to win both an Olympic HW Gold Medal and then the HW Championship of the World?

4: George Foreman called this man the dirtiest fighter he ever fought.

5: This hard-punching Mexican started his career in 1971 as a young teenaged, and went 7-5 in his first 12 fights. He then went on a KO tear and won a welterweight title, before losing his championship to another young fighter.

6: This is the most important question of all....What is Nonito Donaire's favorite restaurant

Have fun guys.
