Wrestlemania XXVII Trivia:

With Edge and The Miz both retaining, and Sheamus vs. Daniel Bryan being turned into a non-title battle royale, this is the first Wrestlemania in the history of the event that no title changed hands.

Wrestlemania XXVII is the first Wrestlemania since Wrestlemania XX that did not have a Ladder Match.

It is also the first one since XX to start with a singles title match (John Cena vs. Big Show for the US Title).

HHH is now in esteemed company… only Shawn Micheals, Kane, and HHH have lost to the the Undertaker twice at Wrestlemania.
