So sorry he's not well, but glad you both have your sense of humour. I totally understand, and yes, definitely funny!
I lost my DH a few months ago, also from cancer. I'm sure a lot of people wouldn't believe the stuff we laughed about together...some of it morbid, some not... but we did it together and it really helped us both keep our outlook positive.
I will be praying for both of you...
