I got that beat! I have 31 minutes to connect from my MSY-DFW to my DFW-LGA flight Thursday! I land in DFW at 6:59a, and depart for LGA at 7:30a! It's a legit connection, but a very tight one. I'm on a MR, and on the advice of FTers here, I'm taking a shot at it!
I'll let y'all know how it turns out.
