One day Udu went to see a patient in the hospital. He had to climb up the stairs as the lift was not working. Half way he felt that needed to go to the toilet and by accident he enterted the ladies toilet. A nurse noticed this and here is the conversation both of them had.

N-Excuse me sir, this is against the rule?
U-No, No this is against the wall
N-Sir you did not understand, this is for ladies?
U-Yes, (turning at her) this also for ladies
