When I see Dale in the comic, my mind gives him his own theme/mood music, and I think if QC were animated, his lines would be delivered very dramatically/mysteriously, which would in turn make him kind of creepy, but if done properly it would be less creep and more mystery/comedy/melodrama. This mood change would of course only apply in his interactions with Marigold, though. His CoD secret menu bit and the first part of his pizza delivery would just be the normal mood of the comic, but then when he and Marigold see each other, suddenly it goes to that other mood. This is just how it goes in my head, and to me it makes Dale an awesome character, not in spite of his perceived creepiness, but in fact because of it, and the way it's played for comic effect. My head is a strange and terrible place, though.
