Because Gaps aren't portals.

Yukari *is* the woman behind Aperture Science. She's just giving a demonstration here of their latest product.

You are now seeing/hearing Yukari going on a Cave Johnson-esque rant.
About hats.

"When life gives you hats, wear them!
Fuck strings or straps! Just use red ribbon. The type that costs you about 7 million dollars!"

Can't tell if you're being sarcastic. Well, Yukari uses her gaps as portals anyway. So its redundant.

That's the joke.

That's the joke, buddy.

Yukari...now 200% more lazy.

Yukari: Ran...open a portal for me, will you?

Just for fun how long do you think it will take before Ran snaps, and decides to place the second portal to the Hell of Blazing Fires?

Yukari, that was a clever move that won't come back to bite you in your ample posterior.
