In the lighter mood: Pat and Mike

Pat and Mike get jobs at the local sawmill. The foreman warns them to be careful of the blade, because it’s easy to get too close.
They are careful, until one day, Mike slips and his arm gets severed by the big saw. Pat quickly puts the limb in a plastic bag and rushes it and Mike to the local hospital.
Next day, Pat goes to the sawmill for work, and there’s Mike waiting for him! Pat couldn’t believe it, but there’s Mike out the back using his now re-attached arm. “Why aren’t you in the hospital?” he asks.
“Oh, my family’s always been fast healers – nothing stops us” replies Mike.
A couple of days go by, and then Mike slips again and severs his leg on another big saw. Pat puts the limb in a plastic bag and rushes it and Mike off to the Hospital. And again, the next day Mike is back at work. “How do you do it?” Pat asks.
“Oh when you have a good constitution you heal quick” says Mike. “My family’s never missed a day of work for sickness or accidents”
But, as usual, within a couple of days he has another accident and severs his head. Once again Paddy puts the head in a plastic bag and transports it and Mike to the hospital.
Next day he goes to the sawmill, but Mike isn’t there. All day Pat looks for him, and after work heads over to the hospital.
“Where’s Mike?” he asks the nurse.
“Oh, poor Mike died” she says.
Paddy is shocked, but not surprised. “I suppose the saw finally did him in.”
“No”, says the nurse, “Some idiot put his head in a plastic bag and he suffocated.
