[Hart and Eggsy enter Fitting Room 3] Gary 'Eggsy' Unwin:
So we going up or down? Harry Hart:
Neither. Gary 'Eggsy' Unwin:

No, Eggsy. [Hart clicks his heels and a blade pops out of his right shoe] Gary 'Eggsy' Unwin:
That is sick. [Eggsy clicks his heels to engage his shoe blade] Harry Hart:
In the old days, they had a phone in the heel as well. Gary 'Eggsy' Unwin:
How do I get it back in? Harry Hart:
It is coated with one of the fastest-acting neurotoxins known to man, so, very carefully. [Hart pushes the blade against the wall to retract it. Eggsy does the same]
