Practical jokes
While just about everyone I know has a good natured practical joke, not everyone enjoys being the guinea pig.
Through the years of working around people and especially the mechanic jokes (we can't forget) I have heard. A few to be sure and thought I would share some.

Blinker fluid
Blinker fluid is probably one of the most common pranks I've seen tried. Infact it's become so common that just about everyone knows about the stuff. So I thought I'd help you out with a jug! Free shipping too! )

Winterizing the air in your tires
Did you know that if you didn't get the air winterized in your tires when you had the coolant checked your vehicle performance could be drastically reduced!? Lol!!! No wonder my fuel economy is so bad...

Muffler bearings
Just about when you think you can't stand a noise anymore you take the vehicle to the shop and realized the unexpected. What else could possibly go wrong!!!

An I'll share one last one for now

The rooster egg
So if a rooster laid an egg on the top of the roof which way would it roll? I've actually heard this many times before I had an unforgettable experience.... A commercial chicken farm my Dad did a great deal of work for while I was a bit younger was collecting his daily egg production and occasionally threw a small egg away... While observing the practice, we were curious as to why he threw them away? His answer... They're rooster eggs!

Well I'll leave you with that for now...lol hope you enjoyed it. Any questions please feel free to ask! As always please upvote, resteem, and don't be afraid to say something... 😀 I'll do my best to respond.
