"Siriussssss" (Derek whispering) (AKA "Serious")

Back in the early days of Siruis, the taglines of the satellite service's commercials used to have a whispered "Sirius." Then DNR (mostly Derek) used to also whisper "Sirius" whenever someone used the word "serious." Sometimes he would whisper it for rhyming words as well, such as "curious." This has carried over into DNR 2.0, which is interesting since both Derek and Romaine have hard feelings about Sirius (AKA "the Facility.")
