Things To Do On Monday, September 9.

I Don't Care, It's Lyle Lovett.

According to a team of scientists at Washington University's School of Medicine in St Louis, one of the main differences between people who are fit and those who are obese may lay within the different populations of bacteria residing in their respective guts. Experiments performed on mice, they say, have proven that the microbes from obese people's digestive tracts did, in fact, promote weight gain in the animals.

While the university has yet to conduct any tests involving humans, they believe that the end America's obesity epidemic just may be to have obese people eat the poop — or more specifically the microbes found within the poop — of skinnier folks. True story.

Of course, there are other ways to stay fit that don't involve digesting a stranger's fecal matter. Y'know, like diet and exercise, and staying active. To that end, why don't you turn off the TVs for the night and check out one of the events below?

Lyle Lovett and His Acoustic Band at Bass Performance Hall
Despite not having one of his singles chart since the '80s, the singer-songwriter has had at least four albums certified Gold by the RIAA. Tonight, he'll have his new acoustic group in tow, performing his songs like you've never heard them before. If all that weren't enough , just consider this: Lovett grew up in Klein, Texas, a town named after his great grandfather. It doesn't get much more Texan than that. — Cory Graves
