A thief stole a sin and a cos.   He took the identities to a beach.   They were too heavy for him to carry.   He wanted to keep them in the ground but the ground was very small and he could only keep either the sin or the cos.   He could have kept one on top of the other but there was a problem.   If he would keep the sin on top of the cos, he would get tan (tanned).   And if he would keep the cos on top of the sin then he would get cot (caught).
