1- Let me know your most favorite bumper stickers you’ve come cross and they are not too long.
2- I’ve told this one: " Drive carefully, funeral costs more than being alive !! "
A- Please correct any mistakes in the sentence.
B- Can I spare one word by replacing “living” with “being alive”? [ if no, I’d love to know why, so that I learn more]
The mods will probably move your thread to a more appropriate forum. You’re in Tehran? Wow.
Yes, “Funerals cost more than living.” would be correct English, possibly better than “…being alive.” as the latter is a bit more passive construction.
I always liked “Horn broken, watch for finger.”
Reported for forum change.
“A funeral costs or than staying alive.” Although I’m not sure that’s true.
One of my personal favourites: “Don’t Vote. It Only Encourages Them.” 
“Keep honking–I’m reloading.”
“My other car is a horse.”
“I can lose weight, but your ugliness will last forever.”
Not particularly funny, but relevant: “Ask me about my horse! Have you got all day?”
I saw a “Support Pirates” ribbon, a variation of support the troops magnetic ribbon.
This is better suited to IMHO than GQ.

“I’m a plumber. Your shit is my bread and butter.”
wasn’t a bumper sticker, but the printing on the back of a private delivery truck.
“Driver carries no cash and is completely naked.”
Reunite Gondwanaland!
I saw one a few months ago that said:
THIS IS THE BACK OF MY CAR
I thought it was hysterical. The person I was with didn’t. It replaces my previous favorite:
HONK IF YOU LOVE HONKING
Take my advice, I’m not using it.
Horn broken. Watch for finger. (My personal all-time favorite.)
And a favorite recently-spotted one: Honk if you love Jesus. Text if you want to meet Him real soon.
I liked “Get off my Bach” and it had a picture of Bach on it.
I saw a bumper sticker that just said “Rowsdower” and I nearly peed my pants because this is a very specific reference to a Mystery Science Theater 3000 episode. The funny thing is that I had only seen that episode a few months prior to seeing the bumper sticker.
This wasn’t in Canada, by any chance?
My favorite of all time was one that said in big bold lettering, “Please generously support your local community mental health services provider!” and then in teeny-tiny print underneath (I could barely make it out) it continued, "Or I’ll sneak in your house in the middle of the night, buck naked, and force you to eat 27 pounds of rotten, rancid seagull meat while masturbating to old re-runs of “Hello, Larry”…
(OK, OK I can’t remember exactly what was printed in the tiny printing, but it was something about sneaking in your house at night and killing you, and I took a bit of poetic license, as its probably been 20 years since I saw this bumper sticker; That said, it was pretty fucking funny, at least to me. The layout and style of the “Support mental health services” looked totally professional, exactly like something a real hospital or charity would come out with.)
My personal favorite was on a car that had significant rear-end damage. It said Warning: I brake for hallucinations.
“This car is protected by an anti-theft sticker.”
