Little Johnny goes to talk to his professor about his grade.

The Johnny comes up to the professor,

“What is this, why did your grade mean 80?”

The professor looks at the exam again,

“Yep, an 80 is what you deserve”

The Little Johnny takes the exam back and asks

“If I’ll bite my own eye, will you give me an 85?”

The professor is surprised, but still, he agrees, at which point Johnny then takes out his glass eye – and bites it.

The shocked professor then takes the exam back and marks it 85.

Johnny then says

“If I’ll bite my nose, will you give me a 90?”

The professor is once again shocked,

“He can’t pull out his nose,” he thinks to himself.

He finally agrees, at which point Johnny takes out his dentures, and bites his own nose.

The professor then once again takes the exam and marks the grade 90.

Johnny then makes another offer:

“If I’ll get up on this table, and pee the perfume Coco Chanel on you, will you give me a 100?”

The professor now has to see what this kid can do, so he agrees.

The Little Johnny goes on the table, and pees all over the professor,

“What the hell?! This isn’t Coco Chanel! This is p!ss!”

The Little Johnny then goes

“Fine, we’ll leave it at 90”.
