The discussion of bagel scooping reminds me of something we used to do back in the day, when bagels were much smaller: Slicing the bagel into thirds. This provides more surface area to pile on the lox, whitefish, etc.
Seems to me this would work even better in the era of behemoth bagels such as Ess-A's.
Similarly, mega-muffins would be great sliced into thirds, especially if you grill your muffins such as is common up in Maine. Again, more surface area for butter to melt into. Mmmmm butter.
