rowrow ship

A huge cargo-vessel powered by many oarsmen.

(from an old "Tracy Twins" cartoon in "Boys Life" magazine; the twins are imaging what it might have been like to paddle a Viking longship)
First mate: Well, boys, I have good news and bad news for you --- the good news is, the captain has allowed you all thirty minutes for lunch!
Rowing crew: And what's the **bad** news?!
First mate (reluctantly): Uhhhh... the bad news is that after lunch, the captain wants to go WATER SKIING!
(And of course, the crew would be none too pleased to hear this, since it would take the term, "rowrow ship" to a whole new level --- imagine how frenziedly they would have to paddle to move the ship fast enough for someone to actually water-ski behind it!)
