Fastest MMA Knockout of All Time (Two seconds) was set by Ryohey Masuda in 2008 in match with Takahiro Kuroishi.

Career Heavyweight Boxing Record (49-0)

One false move from someone like Rocky Marciano would send him to the canvas before he even knew what happened. So for a champ to not only go 49-0, but to also record 43 knockouts in the process, is simply not seen anymore. 

Longest Tennis Match (11 hours and 5 minutes). John Isner (USA) and Nicolas Mahut (France)

They'll always have Wimbledon. While neither Isner nor Mahut has gone on to do much of anything in tennis, their epic 70-to-68 fifth set tiebreaker is one of the all-time craziest things to happen on a tennis court.

Most Assists in an NBA Career (15,806)

John Stockton

In this age of isolation, one-on-one focused basketball, the assist has become something of a dying art. Stockton was nothing short of a master of passing the ball, leading the league in assists every year from 1987-88 through 1995-96. 

Most Goals in a Calendar Year (127)

 Pele

There was a lot of fanfare last year when Lionel Messi scored 91 goals in the calendar year. He was (rightly) celebrated for an extraordinary accomplishment that was the product of incredible skill, perfect health, and a whole mess of matches in which to play. And after all that, he was still 40 percent short of the goals he needed to break Pele's record.

Most Red Cards in a Soccer Match (36)

Damian Rubino, Referee

Considering a team has to forfeit a soccer match if they are down to fewer than seven players on the field, this is a real head scratcher. The volume of people needed to be sent off to reach the magic number of 36 defies all logic.

Most Consecutive Tour de France Wins (7)

One crash during this race can absolutely ruin your chances, and yet Lance was able to avoid any such problems for seven full years. 

Most Wins by an NBA Team (72-10)

Chicago Bulls

This Bulls team was incredible on a number of levels: they lost two home games all season, dropped two in a row just once and really should have had 73 wins (their starters all played limited minutes in their 10th loss, and they still fell by just one point).
