Songs from the 90s

Actually, this is more wacky stuff spotted here in Taiwan, but I've managed to observe a theme on this one, so here goes:

---

• Found this one in one of the local stores that carries pet goods.
  
  

---

• You can...
  ...in the morning, you can...
  
  
  ...in the night, you can...
  
  
  ...when you want to...
  
  
  ...

• I was kind of thinking about the theme from "The Love Boat", but somehow cheezy 70s disco music rings more true...
  
  
  I'm not sure what they are implying here, but I do know that there's know way I'm drinking this...
