Blood type jokes

My ex got into a bad accident recently. I told the doctors the wrong blood type. Now she will really know what rejection feels like.

My cousin died last week; he needed a blood transfusion, but we didn't know his blood type. He just kept saying, "B positive, B positive," but it's hard to be positive with him gone.

A monk, priest, and rabbit walk into a blood bank...

The rabbit turns to the other two and says, “I think I’m a type-O.”

My dad died recently.

He was in an accident and lost a lot of blood but nobody knew his blood-type.

I’ll never forget his inspirational last words,

“Be positive”.
