[Dexter's Lab]: Why haven't it occurred to Dexter to require y-chromosome for entry?

Dee Dee has her way around more or less any security system Dexter has tried. But Dexter has never tried adding a genetic scan making a y-chromosome mandatory (in addition to his regular systems). This would effectively block off all girls including Dee Dee.

Have you seen the experiments he runs?

I would say the odds of him eventually giving himself a y-chromosome, or making a bunch of clones of his crush he needs to deactivate in his lab, or making a doomsday machine that can only be deactivated by a his mum, or some such bullshit are very high.

When your science goes as consistently and weirdly wrong as Dexter's does, you don't want to rule out too much.
