I need help. Today I took the opening line from "The Day Of The Triffids" and decided to make it a big ol' gel transfer. It came out pretty dope and I was very satisfied. It goes:

"When a day you happen to know is Wednesday

starts off by sounding line a Sunday, 

there is something seriously wrong

somewhere"

Pretty amazing, huh? Like I said, it came out pretty dope:

Looks pretty good, right? I showed it to my TA and he pointed out a soul crushing detail. There is something seriously wrong somewhere. Can you find it?

I spelt "wrong" incorrectly. Sure, that sucks. Then I realized, wait, is that awesome? Could this mistake be a high concept piece of ironic genius? 

I don't know. You tell me.
