A university art student asked Bubba if he could paint Bubba's portrait for a class assignment. Bubba agreed, and the art student painted and submitted the portrait, only to receive a C-minus.
The art student approached the professor to ask why the grade was so poor.
The teacher told him the proportions in the painting were incorrect. "The head is too big," the professor explained. "The shoulders are too wide, and the feet are enormous."
The next day, the art student brought Bubba to see the professor.
The professor took one look at Bubba and said, "OK, A-minus."
