This man got the best birthday present EVER!

A birthday is a very special day to celebrate, especially if you have a party and celebrate it with your whole family.

However, the moment becomes an unforgettable event when you discover that you are soon to become a grandparent!

That's exactly what happened in this case! While singing the famous song "Happy Birthday to You" his daughter calls him "grandpa" instead of "Dad"!

When he realizes what she had said and therefore what was happening --- it is total joy! Happy Birthday, grandpa!  :)
