At the 1:30 mark, Bill Hader tells Jimmy Kimmel how he briefly became a big sports fan, most notably of the NBA and specifically, the Thunder. Essentially, he was high.
I will say this, though: I saw Hader at the 2012 Finals and he certainly came off as a very clear fan to me. Then again, the trials and tribulations of the last few seasons can cause even the best fans’ loyalty to wane. Take another hit of Prednisone, Bill, and get back on the wagon for next season. It promises to be better.
