Santa with Heavy computer

Santa and Banta work in a software company in IT department. One day, they had to move their m/cs to another building. Banta was having a tough time carrying his machine.

Santa : “My m/c has 500 MB disk. See how easily I am carrying it. Yours is only 250 MB. Can’t you carry even this much?”

Banta : “But yours is empty and my disk is full”!!!
