This mistake is an interesting one. I was hurry while typing and I typed catched as the past tense of catch. I should not make such a silly mistake, because of two reasons. One is, I watch cricket and it teaches us the past tense of catch is caught. Also, I have practiced this word a lot, when I was a kid and was in school. Just now I realized why I did this mistake. It's because of the word cached. I use it a lot because of my profession. Then I tried to correct catched, but what typed was cought. Looks like it's a typo and I corrected this with the help of spelling suggester of my browser.
