I'm having a lot of toruble learning intervals.
Sure, I know almost all my theory, the theory behind intervals and all that, but God help me, my ear is shocking.

I'm wondering if anyone has any idea about other songs to use in order to learn intervals?
For example, someone might say a Major 6th sounds like the beginning to 'My Bonnie', but no matter how many times I hear either, it doesn't stick.
So are there any other songs or tricks people use to remember them?
