This month's phrasal verb, see through, has two meanings. You can probably guess both meanings from the picture. Here's an explanation to help you out, just in case.
Of course, we can use see through to mean 'look through':
'The window is too dirty. I can't see through it.'
See through, when used as a phrasal verb, also means to be aware that someone is trying to lie or fool you:
'The teacher could see through her student’s excuse very easily.'
In the cartoon, the ghost's wife (do ghosts have wives?!) can see that he is trying to lie to her – she can see through his story.
