He's from Team Rocket
Woman: "When I asked him what he was doing out there, he said 'I was trying to get a Pikachu'".
He was sinusoidal.
A dog that chases cars - and catches them!
Because he catches all the snitches!
So they can Pikachu
PIKA PIKA PIKA (Credit to my 5 year old son)
When he sits down it takes too long to get back up.
Team Rocket since they're always blasting off.
