Sliced bread isn't even that great. Such a weird way to judge how great something is. Also not great are Roman's pops. He gets pretty tepid reactions most of the time for a guy who is being positioned so hard.
It used to be you got a hunk of bread and you had to slice it yourself.
With the advent of the bread slicer, man was forever freed from the tedium of having to slice his own bread.
As far as Roman Reigns goes, at least they have him enunciating.
ALSO: Sliced Bread (From Wikipedia):
It was first sold in 1928, advertised as "the greatest forward step in the baking industry since bread was wrapped".[1] This led to the popular phrase, "the greatest thing since sliced bread".
