TOPSHOTS US President Barack Obama scream "Zot, Zot, Zot", as he makes the symbols of the Anteater, the mascot for the University of California-Irvine, after delivering the commencement address in Irvine, California, June 14, 2014. The student chant "Zot, Zot, Zot!" is the sound made by the tongue of the anteater in the comic strip B.C. by cartoonist Johnny Hart as it flicks out to catch an ant. AFP PHOTO / Jim WATSON
