Sliced Bread 2: The Greatest Thing Since Sliced Bread

For some reason it seems that tonight's events can be best recorded by a series of haiku:

Cellphone rings at night
Mayhem at the Robertson
Planetarium

Masks of villainy
Keyring, Margay, Sugarbear
The Professionals

Greyghost is inside
Saving millionnaires' jewels
My instructions clear

Freight elevator
Helicopter on the roof
I have some duct tape

Lovely spring evening
Background city noise pleases
Mummified chopper

When Greyghost signals
Let's get the hell out of here
Or they'll kick my ass

Well, that's just perfect
Elevator is busy
Need another way

Observatory!
Handy emergency door
Lock it behind me

Later in the street
Supervillains in handcuffs
Sirens aplenty

Crowd is breaking up
Helicopter immobile
Police scratch their heads
