Reminds me of the old joke:
Captain on PA: Ladies and Gentlemen I'm afraid the Nr 4 engine has failed. Our flight will be delayed by an hour ...
Sometime later:
Captain on PA: Ladies and Gentlemen I'm afraid the Nr 3 engine has failed. Our flight will be delayed by another hour ...
Sometime later:
Captain on PA: Ladies and Gentlemen I'm afraid the Nr 2 engine has failed. Our flight will be delayed by another hour ..
One Pax to another: It's to be hoped the other engine doesn't fail otherwise we'll be up here all day ... !!!
