Typo in Rifftrax instructions

[MarkAndrew]

Under the 'It's Easy' sidebar

It says "Rifftrax work with any"...It should say "Rifftrax works..."

[Minnesota]

sounds alright to me "as is"
is this one those obscure-common typos that piss off educational types? (ie; teachers )

[Douglin]

Given that Rifftrax is both plural and singular, both ways are acceptable.

[Pak-Man]

Yeah. It's like saying "Fish work with any..."

[AmandaGal]

It makes more sense to me the way it is.  I think they are trying to say, "All rifftrax work with any" as opposed to "this rifftrax works with any"
