Coverups a possibility, wouldn't be too bad...I'm just wondering at what point did you think;
"Yeah! A clown with his hands down his pants!! That would be the shits!!"
I'm glad you realize how utterly stupid this tattoo is now and I can only hope that whomever decides to cover it for you cuts you one hell of a deal cause that is going to be freaking expensive, if do-able at all.
It's well done but if it doesn't mean something to you I'd definitely do what I could to change it. I think a tattoo should be a way to express who you are or mark a time in your life. Maybe you should keep it to remember that time..
