Once he no longer had Larry “Bud” Melman to carry him, Dave was toast.
I think the viewers always liked Sirajul, Mujibur, Larry "Bud" Melman and Dave's Mom more than they ever liked Dave himself.
“Once he no longer had Larry Bud Melman to carry him, Dave was toast.”
After Bud left the show I found out that Letterman wasn’t funny at all, just pathetic.
