From Wikipedia about the dee de dee de lyrics in the song:

Several weeks later, Simon re-emerged with two new tracks, "Punky's Dilemma" and "Overs", neither of which Nichols was particularly taken with.[5] Nichols asked if the duo had any more songs to offer, and after a break from the meeting, they returned with an early version of "Mrs. Robinson". They had been working on a track titled "Mrs. Roosevelt", and returned to perform it for Nichols. He was ecstatic about the song, later commenting, "They filled in with dee de dee dee de dee dee dee because there was no verse yet, but I liked even that."

Classic pop music. Dee dee dees and ooh ooh oohs and mow mow mows make for great hooks every time.
