That should be Woah 4

 Did the captain fall asleep?

You'd think so wouldn't you Yogi?  I was searching for something else and came across this

I've seen that one before Saint 

So as not to disappoint you . . . apparently it was a woman at the wheel

Boom boom

w.t.h.? How could that happen? Lucky the ship had that stick out bit at the front.

think it was engine failure, it happened a few months ago 

Or even Whoa!

Always saw it with an "h" on the end

Is without the American version?

Just had a wee google on the subject - it would appear to be a bit of a grey area. I've always been of the understanding that WHOA is the 'correct' spelling.

I'm with Renton thinking it should have an 'h'.

I made this door stop iin craft class the other day

Along with a pin cushion saying, "Ouch"

And a draft excluder saying, "Brrr..."
