Happy Martian Luther King Day

*Sees Alien*
...
ayy lmao

Can someone please explain to me what Martian Luther King day is? I'm very confused since I'm not from the states and keep hearing a lot about Martin Luther King day

Junior...

I have a dream...
that one day people will learn to spell

Is it just me or does that alien look like it's on A History Channel show saying "Humans".
