Cartoon disney question: snow white asks the dwarfs a question. 2 of them are lying and 3 can only say the truth. the continuation of the picture, because the refuses to publish my question fully. answers: 1. sleepy & happy 2. sneezy & doppy 3. bashful & sleepy 4. happy & sneezy

The complete question:

Bashful: Dop.ey lies if Sleepy honest
Dop.ey: If Happy doesn't lie, then Bashful or Sleepy do
Happy: Sneezy lies as does Bashful or Dop.ey
Sleepy: If Dop.ey honest, then Bashful or Happy do as well
Sneezy: With Bashful, Happy or Sleepy there is at least one liar. 
The question asking the liar one.

Before we start, let's use the name initial to make this easier. Sleepy would be Sl and Sneezy would be Sn since they have the same initial. To solve this, let start from Sneezy since his statement is involving 3 people independently(without condition).
If Sneezy liar, that means there is no liar from B, H, and Sl. That means B, H and Sl would be honest, leaving D as a liar too.

Bashful: Dop.ey lies if Sleepy honest (True: Sl is honest, D is lying)
Dop.ey: If Happy doesn't lie, then Bashful or Sleepy do(False: H is honest but B and Sl is honest too)
Happy: Sneezy lies as does Bashful or Dop.ey(True: S lies and D lies)
Sleepy: If Dop.ey honest, then Bashful or Happy do as well(True: D is not honest, B and H is honest)
Sneezy: With Bashful, Happy or Sleepy there is at least one liar. (False: no one lies)

Luckily we have the answer right away. Sneezy and Dop.ey lies which mean 
The answer is 2. Sneezy & Doppy
