I probably should have called them back and told them it was a joke

Just in case there are any guys from 12 Sqn reading this, I was kidding, we're not being privatised (yet - ask me again after the election...), we're not being bought out by Disney, I won't be going into briefings wearing Mickey Mouse ears and we won't be diverting all telephone enquiries (including target weathers) to a call centre based in Mumbai.

Honestly, I was going to say that they should check the date but it was too much fun.
Wasn't as good as last years though.

Think I'll shrink wrap my boss' desk next year.

April, fool.

Yesterday being the first of April there was a fair bit of pressure on us to try to do something "funny" at some point. This was a problem. I was trying to think of something that I could do but nothing presented itself.
I was running out of time.
I drove over to give a brief at one of the squadrons, got ready with the usual banter. They asked what April fools joke I'd be doing and I responded with the usual "I would but as a corporation we have no sense of humour" (Men in Black misquote FTW!)
Got to the end of the presentation and on the last slide it came to me.
"For Friday we've got a front moving in from the west; and next week we've got the TV weather girls coming up for their routine defence rotation."

I managed to dead-pan the entire thing and the pure joy on the faces of the guys was beautiful. They started planning to re-arrange time off and asking me details such as which girls, how long they were staying and would they be visiting the mess?

After a few seconds I looked up, smiled and simply said, "Gotcha!"

Much good natured verbal abuse ensued and as I left the briefing room I heard someone (might have been the boss) clearly enunciate, with a hint of begrudging respect, "Bastard!"
(Today the squadron boss admitted he had been hooked nicely.)

Didn't quite work as well with the other squadron, but then again I'm not sure if they realise it was a joke...
I'm not going to say which squadrons were involved but I think it's fair to say that I am pretty dang happy with that one.
