If you wish to use the classic "ha" then it would be five dots and a dash ( * * * * * - ) If you wish to use the more modern "lol" then it would be dot dash dot dot dash dash dash dot dash dot dot ( * - * * - - - * - * * ) If you just wanted to kind of giggle with a "te he" then it would be dash dot dot dot dot dot ( - * * * * ) Or if you just want to spell the word laugh then it would be dot dash dot dot dot dash dot dot dash dash dash dot dot dot dot dot ( * - * * * - * * - - - * * * * * )
