Santa starts working in a Museum enquiry counter.
One man asks Santa - How Old is this Dinosaur''s fossil?
Santa - Hmmm... It is 70 million years and 23 days old
Man - How can you tell so accurately?
Santa - When I joined the museum 23 days back, they told me that it is a 70 Million Year old fossil and not to touch it.
