cracking joints... knees and elbows

[babyfaced monster]

when im sitting for a period of time and then stand up, my knees crack. Same with my elbows. I love to squat and the higher ive progressed, my knees crack louder and louder although they feel just fine. Whats up? Is there anything that can lubricate my joints?
