Example Input: Gonna bring the brown bears into town and smell like hell at Spring Creek Prison in the summer westerlies. Not the best of places to make a deposit. It would seem no one involved in this operation has ever been in the vicinity of a rotting whale. Expect to hear more about this as the summer peaks and the whale seriously decomposes.
Example Output: Yes

Example Input: our road rage factor has jumped.  yesterday evening...saw an incident.  I wound up 2 cars behind the 2 vehicles that were having problems with one another and the angrier fellow saw my cell phone in my hand and decided he was going to speak with me next. of course I could not get my car out of the red zone and just started babbling into the phone..."yes sweetie, grandma will there as soon as possible , there is some construction or something holding up the cars, grandma loves you too sweetie.." said something like that with one eye on the guy turned towards me and i'm ready to hop out of that car if necessary to defend myself. then poof, the guy turned away from me, screamed some more at no one in particular and got back in his rig and took off. poof like that. the other fellow took off and myself and the other witness were left at a red light looking at each other through the rear view mirror and just ...stunned. could have been so ugly and it was started and done in a minute.  Rage.
Example Output: Yes

Example Input: I saw the Alaska Federation of Natives ditch Parnell because they had dealt with him for 5 years on the release of the Fairbanks Four and got nowhere.  Walker promised them if they got him elected he'd put his business partner to work as Attorney General and get the 4 released. Corruption witnessed by all Alaskans. 
Regardless of the party, regardless of the race, regardless of the state, it's all full of corruption.
Example Output:
No
