Battle of the Wills

As Mr. Incredible turned on the TV to watch the final round of the US Open:

Dash (always the optimist): Elmo!
Mr. Incredible: Golf.
Dash (with a hint of frustration) Elmo!
Mr. Incredible (not to be deterred): Golf.
Dash: Elmo!!
Mr. Incredible: Golf!!

I won't reveal the exact length of this two word conversation, but it went of for quite awhile.
