London Bus

[Seafood]

Two African men were talking on a London Bus. One said "I think it's wombaa". "No" said the other, "it's definitely woooomb". They went back and forth with this argument until a little old lady sitting behind them said " Excuse me gentlemen but the word is pronounced woom, rhyming with room." One of the men turned to her and said " What would you know about it lady? I bet you never heard a Hippo fart underwater in Lake Tanganyika."
