Which one or both?Axel's or Xigbar's?!!

both

"Got it memorized?"

Both.

common old coot as if and the got it memorized they are both the best catchphrases ive ever heard

I go with Xigbar's. Axel's little phrase is SO overused these days, I never wanna hear it again and wish he'd go back to saying, "commit it to memory" like he did in the GBA Chain of Memories. ....But that'll never happen. =____=;;;

I don't have "as if" memorized...
