Strange Mets/Phillies combo merch for sale at London Series - ESPN

If your friend is a New York Mets fan, get them a Mets jersey. If they're a Philadelphia Phillies fan, a Phillies jersey would be a fine gift.

But what if, against all odds, they're equally passionate about both teams? What would you get them then?

If such a person even exists, given the fierce rivalry between the teams, you might want to stop by London.

Fans visiting the area, which is promoting the Mets-Phillies series in the United Kingdom this weekend, noticed some peculiar merchandise for sale that had the logos of both teams on them.

Could you imagine a combination Boston Red Sox/New York Yankees hat? A warmup jersey that's half Los Angeles Lakers purple and half Boston Celtics green? A poster celebrating the Montagues and Capulets?

That's the vibe we're getting from these. One fan ended up buying one, but only to offer it up as part of a giveaway on social media. You know, in case you're interested.
