Why Santa Says Ho ho ho

Hello
  There was a question in my mind for quite a time. That,Why does Santa says ho ho ho
  If he laughing ?
  Are these his let words ?
  Or just random words
  After a lot of meditation i have found the answer
  "Ho Ho Ho" are the words said to Santa's reindeers,not us. People who had a connection/intraction with a pet animal devolp a language to intract with them.
Like in India they shout "Hatt Hatt Hatt" to sacre away animals and "takk takk( sound made by tongue) to get bullock to move.
    so , Ho Ho Ho is the signel or order for the reindeers to Start moving or stop.
Love you reader.
Happy New Year
