This type of mistake happen because of pronunciation. Here one hotel in is opened. Owner painted name in Punjabi and Hindi. Name of Hotel is Prasadam. But when we write it in Punjabi, we pronounced it Parsanda. They also painted in Hindi Parsadan.

These spelling mistakes make us laugh. See this this sign Board of a hair cutting saloon

Those spelling errors are the source of laughter.

if something makes us laugh then i think that that mistakes are good and i wish that the people continue to make mistakes like that.

Some times mistakes are deliberate just to attract people. Once a businessman hung his banner upside down. More people were attracted and his advertisement was successful. 

I think laughing on small mistakes of others is a laughing matter in itself. Remember no one is  perfect in this world.

I agree. The purpose of committing mistakes deliberately on the display boards and banners is to draw the attention of the public. In this process, laughter generates. A display board on a Hair cutting saloon announces, "We cut the children too here."
