I'm glad RedBaron brought up PC chips. They have a vast selection (I bet 10 or 12 different varieties), but no traditional flavours per se. This reminded me of two specific chip flavours, and their subsequent downfall.
PC's "Ballpark Hotdog" were on display the Sunday morning of Week 14 of this past NFL season. I was already drunk, so a stop at No Frills on my way home from the bar (I do a pool there, jerks) made sense. Who in their right mind would turn down anything flavoured "Ballpark Hotdog"? In my case, who not in their right mind, either? I digress. These were good, but they're not a chip you can eat a bag of over the course of a Sunday afternoon. They get gross in a hurry. Ironically, I suspect they'd be perfect for a BBQ, where you can have a handful at a time among other dip and platter-type items.
Along the same lines, my old man introduced me to Doritos' Late Night Cheeseburger during Week 2 of the very same past season. Spectacular. BUT! I fell asleep on the loveseat (!) immediately following SNF. Drunk (and therefore hungover the next morning), on a loveseat, with five hours sleep, with an open bag of DLNC near my head - who wants to guess how awful I felt the next morning? Not the chips' fault, but I haven't been back.
