In a study it was learned that white women have the thickest, and White men the thinnest skulls. The skulls of women are thicker than those of men in both ethnic groups. The differences are shown to be statistically significant. This is funny because it’s the men who need them, especially after having a few too many Bonehead cocktails.
The bonehead is a drink that goes down so easy you're libel to do a drunken bonehead stunt. Wear a helmet.
