Try singing this Chorus from Tom Lewis' classic sailor song in your best Scooby/Astro voice:
I'm marching inland from the shore, over m' shoulder I'm carrying an oar,
When someone asks me: "What - is that funny thing you've got?"
Then I know I'll never go to sea no more, no more,
Then I know I'll never go to sea no more!
Rikey's Rooby/Rastro Rendition:
Rhyme Rarching Rin-Rand Rum Ra Roar,
Rover me Rolder I'm Rarryin' a Roar,
Ren Rum-run Rasks me Rut, Ris dat runny ring you rot -
Ren I Row I'll Rever Row to Reeno roar Roar ROAR!
Ren I Row I'll Rever Row to Reeno ROOOARRR!
