Pardon me, sir, but being as you've just eaten your 41st burrito I'm afraid you have no one but yourself to blame for your stomach upset and soul-crushing flatulence. The management kindly requests that you leave.

Barack Obama is the 44th President of the United States of America.

...........Take a wild guess..........

That's right! Donald Trump will be the 45th president of the USA.

Just a fact - I'm keeping my opinion neutral so as to avoid being shot down by those devoted to either the political right or left.

Also, the war ended in '45.

from Wikipedia:

Forty-eight is the double factorial of 6,[1] a highly composite number.[2] Like all other multiples of 6, it is a semiperfect number.[3] 48 is the second 17-gonal number.[4]

48 is in abundance having an aliquot sum of 76. It is the lowest composite number to fall into the 41-aliquot tree having the 7 aliquot number sequence,(48, 76, 64, 63, 41, 1, 0). 48 is highly abundant with an aliquot sum 158% higher than itself.

48 is the smallest number with exactly ten divisors.

There are 11 solutions to the equation φ(x) = 48, namely 65, 104, 105, 112, 130, 140, 144, 156, 168, 180 and 210. This is more than any integer below 48, making 48 a highly totient number.[5]

Since the greatest prime factor of 482 + 1 = 2305 is 461, which is clearly more than 48 twice, 48 is a Størmer number.[6]

48 is in base 10 a Harshad number.[7] It has 24, 2, 12, and 4 as factors.

48 is a Narcissistic number (but subtracted instead of added) as: |42 − 82| = 48
