'betty', I don't think there's anything out of order here.
I've done 21 years, 22 when I'll be leaving against my will a year from now. 'Black' humour, and I would opine this thread contains no more than light aircraft grey*, has been part and parcel of military life for an aeon, today is no different.
I'm gutted, but laughter can help the pain.
