Rappers bringing "surprise" guests out on tour
Examples: Every rapper
You might be a rapper if... everyone knows exactly how your show is going to play out, even though they've never even seen you perform. These days, it's more of a shock if Jay does not bring out Kanye, who brings out 2 Chainz, who brings out a hologram of President Eisenhower, who introduces the guitar tech from the Spin Doctors, who gets the crowd pumped for Alfonso Ribeiro's cousin's uncle's family friend to chant "Hova, Hova" at the end. Whatever—we saw this same show in 2002.
