From The Cleveland Show, "Nightmare on Grace Street" episode...
Donnie, an annoying guy who wants to be Cleveland's friend, but Cleveland always blows him off tries hanging out with the Browns when they're trick or treating. At one house, Donnie jumps out and yells something to the extent of..
"Trick or Trout! Ha HA ha Ha! No seriously, we want candy not fish...unless they're Swedish Fish [puts finger under nose like a mustache and does a bad Swedish Chef impersonation" Borkidy smorkdy borky doo..."
or something like that. Point is, he did a bad Swedish Chef accent.
