Unsure of what to watch tonight? Here are my Monday recommendations.

How I Met Your Mother (CBS, 8pm EST) – In tonight’s episode, Robin and Lily give challenges to Barney, which he — wait for it — accepts. Also, it’s the return of Bryan Cranston!

2 Broke Girls (CBS, 8:30pm EST) – Max and Caroline go to a hot restaurant that’s almost impossible to get into. Will shenanigans ensue? Most definitely.

Over on TBS, there’s a Big Bang Theory marathon from 9pm to 11pm.

South Park‘s Coon and Friends trilogy is on Comedy Central starting at 9:30pm. If you’ve been missing Mysterion as much as I have or have a fondness for Cartman and Cthulhu, this is the trilogy to watch.
