Contact the company and inform them- chances are high that they'll edit it to either cover your crack or crop you out completely. Also, may I suggest either a belt or smaller pants? People generally don't enjoy seeing someone's personal moon.

Next time you're in the office, ass them to fix their website. After all, I don't they they want such a crack in their professional façade.

Butt crack pictures make it to the whole Internet — your trousers would have had to drop further for the hole Internet to care.

Not to mention the red dots all over your body.

Well, shit, there goes your reputation as a crackless automaton.

Unless someone can identify you by your ass crack, I wouldn't worry about it. Should make an interesting dinner tale.

I see a bad moon arising, I see trouble on the way....

You'll get in trouble for doing a half-ass job.

Not a problem if you work for a plumbing company, people expect to see that then.

You were practicing for your plumbers license.
