Senses Fail Puns

An engineer who was unemployed for a long time decided to open a medical clinic. He puts a sign outside the clinic: "A cure for your ailment guaranteed at $500; we'll pay you $1,000 if we fail."

A Doctor thinks this is a good opportunity to earn $1,000 and goes to his clinic.

Doctor: "I have lost my sense of taste."

Engineer: "Nurse, please bring the medicine from box 22 and put 3 drops in the patient's mouth."

Doctor: "This is Gasoline!"

Engineer: "Congratulations! You've got your taste back. That will be $500."

The Doctor gets annoyed and goes back after a couple of days later to recover his money.

Doctor: "I have lost my memory, I cannot remember anything."

Engineer: "Nurse, please bring the medicine from box 22 and put 3 drops in the patient's mouth."

Doctor: "But that is Gasoline!"

Engineer: "Congratulations! You've got your memory back. That will be $500."

The Doctor leaves angrily and comes back after several days, more determined than ever to make his money back.

Doctor: "My eyesight has become weak."

Engineer: "Well, I don't have any medicine for this. Take this $1,000," passing the doctor a $500 note.

Doctor: "But this is $500..."

Engineer: "Congratulations! You've got your vision back! That will be $500."

I said: Why knot

B'day, mate!

This joke failed in r/jokes I want to see if you all have a better sense of humor.

So, let's start off with a fact about myself: I'm vegetarian. I've been one my whole life. Now, let's get to the story.

Basically, I was driving down to camp at a Battleship with my dad (for a Boy Scouts trip), and this was during my first 6 months of learning to drive. This was the most intense trip for me (so far), and I was already nervous about driving on the interstate, so I was doing my best to practice proper driver etiquette.

Now, here's where the story gets interesting. I'm cruising down the interstate, going approximately 70 mph in the middle lane, when all of a sudden, I see a deer emerge onto the road from the right. It's running to the left (aka, trying to cross this interstate). The car to the right of me slams on the brakes, so the deer kept running. I slammed on my breaks as hard as I could, BARELY missing the deer. The car to the left of me was unlucky. The deer smashes its head into the left car's headlight and it flips over to the right (over my car). Clearly, it's dead, and as it flipped over my car, a lot of its blood gets onto my windshield.

I'm horrified. I kept driving forward. Trying to make sure I didn't veer off or anything. I look to my dad, and my hands are slightly shaking while I'm continuing this trip. My dad looks over to me, smiles, and says, "Don't worry, my 'deer'. Keep driving."

I looked back at him with the most disgusted face, and he just started giggling. Good god, this was NOT the time for a dad joke, but nevertheless, my dad didn't fail to deliver.

I thought I'd hate him forever after this and people would agree with me, but now this joke gets one of the largest laughs from people at parties. <_<

tl;dr My dad's sense of humor appalls me.
