Boston and LA for sure.

I'm going with Kansas City and Philadelphia

I think the Red Sox and Patriots won it the same year. I think...

All correct! Boston, Los Angeles, Kansas City, and Philadelphia all have had a Super Bowl champion and a World Series champion since 1999.

There are two more correct responses.

Bonus points to Mick for remembering that Boston had a Super Bowl champion and a World Series champion in the same year. In fact, it happened twice, with both Boston teams winning championships in the 2004 and 2018 seasons.

That 2004 team had a lot of Giant connections. Bill Mueller was their starting 3B, and easily their worst starter was RF and future Giant manager Gabe Kapler (0.1 WAR in 138 games, and that's hard to do). Also on that team were Ellis Burks, former 1st round draft pick Adam Hyzdu, Dave Roberts, Dave McCarty, Doug Mirabelli, Orlando Cabrera, Keith Foulke and Alan Embree. All future or former Giants.
