Doctor: “Sir, I’ll say it again, that’s A Fib!”
Sorry, It’s not a good hearted joke.
Because it wasn’t getting enough iron.
Me: I've got a fatigue lab tomorrow morning.
Dad: Wow, that sounds tiring.
He laughed so hard he nearly fell off the pavement.
I asked him if he was suffering from Mussel Fatigue.
I ran a local Tough Mudder-like race in September (called Boldr Dash) which featured many obstacles over a four mile course. One of the obstacles was a huge ladder made out of tires that we had to climb up and over. While waiting my turn to climb it, I turned to the line and said "I hope nobody's TIRED!"
The combination of fatigue and disgust at my joke was everyone's reaction. A group groan, it was beautiful!
