Happy Birthday? Kevin Harvick busts on business manager with embarrassing photos

Today is the birthday of Josh Jones, the director of business development for KHI Management LLC, the company owned and operated by Kevin and DeLana Harvick.

Jones goes by the Twitter handle @Mother_Function and is sometimes the object of intense ribbing by Harvick, the 2014 NASCAR Sprint Cup champion.

And what better time to bust a pal's stones than on his birthday?

It could be a long day for Jones at this rate.
