He said that because of Pi. Raspberry Pi is a program. The first ten digits of Pi are 3.141592653... Hence, the phone number. Hope that helped! ;)

Actually, there is no relation between the Raspberry Pi and the number pi. The name originated from the fact that the RPi could only run Python (coding language) in the beginning. The Python language was named after Monty Python's Flying Circus.
