They're plastic fantastic, tabloid fodder, hopelessly delusional and just won't go away. And that is why Heidi Montag and Spencer Pratt are this year's Official Celebritology April Fools.

Honestly, we didn't have to deliberate much about which celeb deserved this year's honor. In fact, the couple had already clinched the title when yesterday's breaking Speidi news -- that they had adopted Native American names (Her: White Wolf, Him: Running Bear) in an "effort to become more spiritual."

It's undeniable, this motivated couple wanted it. Below, just a few (trust me, there was no shortage of material) of the ways in which Speidi made themselves standout candidates over the past year:

April 2009: The newly-married duo honeymoon in Mexico, swine flu's ground zero, complete with surgical masks.

August 2009: Heidi's "Gong Show"-worthy performance at the Miss Universe pageant:

Sept. 2009: Before he was Running Bear, Pratt claimed he had legally changed his name to "King Spencer" and tried -- thus far unsuccessfully -- to launch his own musical career:

November 2009: Montag, who was already a pretty (if dippy) southern California girl, undergoes 10 plastic surgery procedures in one day. The result? Heidi-bot, who walks, talks and deadpans "beauty is on the inside."

March 2010: Heidi's insistence that she's ready to be a "full time motion picture actress" after filming a cameo in an upcmoing Adam Sandler movie. Next up for the thespian? "I am making the first 3-D beach comedy about a shark that attacks a small beach town and I save the day with my 3-D boobs."

I'd say we chose wisely.
