Last season, when the Bears were still a decent team, Chicago receiver Brandon Marshall referred to the Lions as the Bears' "little brother." Now, with the Bears struggling and the Lions leading the division, a Detroit fan let Marshall know on Instagram that he hadn't forgotten about those comments. He also threw in a jab at Marshall's mom, because that's what people do when they're trying to be tough on the internet.

Most athletes would ignore stuff like this, but Marshall isn't like most athletes. He responded with a challenge.

@AnthonyGKalla: @BMarshall idk if you saw this on ig but here's a reminder http://t.co/GYT7hj3mWe

I give you 5k to get in a ring with me.

@AnthonyGKalla

If I lose I'll give you another 10k. If I win you have to serve a 100 hours at an orphanage.

Deal?

The tough guy, realizing he'd be risking life and limb, or perhaps hoping Marshall would balk, asked for more money. Marshall's got plenty of money, so he called the raise...

"@AnthonyGKalla: @BMarshall that's it? Cmon brandy make it 25 and we can do it in Detroit"

25 it is. Ha! You thought i wouldn't say yes.

...and asked him to apologize to his mom.

The fan didn't respond, so Marshall asked him again.

@AnthonyGKalla

Deal or no deal bro? This is your chance to back up your talk and make 25k.

Finally Marshall got an answer. The fan told Marshall he'd do it if the Bears won three more games, then he made his account private. 

Three more wins? That's pretty much admitting to backing out. The Bears just lost two games by a combined 69 points. This fight is not happening.
