I laughed so hard the first time I saw that scene in Spaceballs.
And then many years later when I was first dating my wife I was explaining some of my favorite spoofs and I came to the scene from ALIEN/Spaceballs. She hadn't seen ALIEN so I had to set the chestbursting scene and then I explained the Spaceballs parody. Apparently I was talking to fast or something because after I got done going over the little alien with the spotlight and top hat she stopped me and said, "wait, which movie are you talking about ALIEN or Spaceballs?"
I seriously rolled on my carpet laughing for like five straight minutes at the thought of her picturing the horrific scene from the 1979 classic ending with the "Hello My Baby" number.
