I had to pay close attention to figure out what he was saying. It is, "Pure... adrenalin!"
In the Geico commercial, the pig says "Whee!" as he passes the man on the zip line.
The pig says "heads up"... on the new commercial where there racing down the road...
Wee wee...then he says "pure adrenaline" with a snort and a giggle...
Mrs. A first calls the pig Max then when he doesn't answer it's Maxwell.
He says "Pure adrenaline", then he just snorts.
Snort HAHAHA
Pure adrenaline
Wee, wee. Pure ..... adrenaline. [snort] heh heh.
Pure adrenalin
The 'pig' character comes from the "This little pig went to market..." fame. This particular pig is the last one that says: 'Wheee' (all the way home). Thus, the pig is saying "Wheee!" down the zip-line.
In Pig Latin, "Happy New Year" would be "Appyhay Ewnay Earyay."
Don't pass out. Actually, I think he's saying, " Uh, heads up." (Not 100% sure)
