Akpos and Mary were both patients in a mental hospital.

 One day  while they were walking past the hospital swimming pool, Mary
suddenly jumped into the deep end. She sank to the bottom and
stayed there. Akpos promptly jumped in to save Her, he swam to
the bottom and pulled Mary out.
When the medical doctor became aware of Akpos' act, he
immediately ordered his discharged as he now considered him to
be mentally stable. When he went to tell Akpos the news, he said
"Akpos, i have good news and bad news, the good news is you
are being discharged, because you were able to jump in to a
swimming pool and save the life of another patient, I think you
have gotten well enough and the bad news is that, the patient you
saved hung herself with her bathrobe belt in the bathroom, I am
sorry, she is dead."
Akpos replied, she did not hang herself, I put her there to dry!
