Dennis Duffy Joins Up All Night As Will Arnett’s Brother

By

Dean Winters is guest starring on Up All Night as Will Arnett’s character’s brother, which is amazing, because the two of them could be gravel-throated brothers in real life, and also challenging, because it will be hard to write this entire post without conflating Winters with his 30 Rock character Dennis Duffy every two seconds. His episode will air in early 2012 (the year of the Beeper King! Shhhh) and apparently his character has a competitive streak (Yeah, competitive about how many beepers he has! Nope). We can hopefully look forward to him making lots of creepy passes at Maya Rudolph’s Ava (and at Baby Amy, because you know how Dateline predators are. Damn it).
