MacGyver, Season 2

Pete:
Woody, these bypass codes are never gonna get us through the front door. MacGyver's got to know that by now, too. I'm sure he's looking for some other way out.

Colonel Woodward:
Pete, you can't be sure of anything.

Steven Lee:
If you're right, Mr. Thornton, MacGyver only has two choices for another way out. The maintenance shaft or the exhaust outlet.

Pete:
Well, now we're getting somewhere.

Steven Lee:
There's a catch. Both of them are mined with explosives from the outside access ports. We only have time to dismantle one.

Pete:
Mined? So you're telling me if Mac tries to exit either way before we diffuse the explosives...

Colonel Woodward:
He's gonna blow both of them to kingdom come.
