Ok let's do some math.
Out of 313.9 million U.S. citizens, 47,391 people are named Spencer.
So there is about 0.0001245 chance that two people are named Spencer.
Additionally, out of 313.9 million U.S. citizens, about 15 million people are fan of Lil' Wayne.
So there is about 0.05 chance that two people are both fans of Lil' Wayne.
Multiply 0.0001245 with 0.05 and you get a number so infinitesimally small, that it is stupid to think that this is not the same ol' spencer. But of course, I may be wrong. Just providing the numbers though.
