He heard his padawan swear in the refresher.
"Anakin I have told you about shouting across our quarters," Obi-Wan reprimanded.
"It was an accident I swear Master!"
"What was an accident?"
"I flushed your lightsaber down the toilet Master!"
Obi-Wan bolted out of his chair, book cast aside as he ran into the refresher in horror. How on earth had Anakin got hold of his lightsaber anyway?!
His padawan burst out laughing.
"April Fools Master," he managed to say amist giggles.
"Humph! Not funny Anakin," he grumbled realising his lightsaber was on his belt.
