Warning: very strong language.
Sometimes the simplest pranks are the best, and this certainly proves it.
One YouTube star has racked up over 200,000 views on his "Angry Dad" page for this video of his father's reactions to being honked at on the road while unknowingly dragging a huge sign saying "honk if you're horny".
Staying true to the YouTube account's name, Angry Dad got quite annoyed by all the people sounding their horns, seemingly for no reason.
And it didn't end when he finally caught on to the prank, clearly expressing his anger when he saw the sign on the back of the car.
