You could print it in the log, via some convoluted method, or display it as ASCII art, or anything! Just come up with a creative method of displaying 42.
Because this a popularity-contest, whichever answer has the most upvotes by March 11, will be declared the winner.
Note: this is not a duplicate. The question it was marked as duplicating was a code-trolling question whose goal was to write code to output 42, not find the most creative way to display it.
Winner: grovesNL! With an astounding 813 votes! Congrats!
