Speaking of Engrish, I think the most 'wtf'-worthy bit of Engrish in an anime song is the 'you must fight against yourself' bit from the Gensomaden Saiyuki closing theme.
Nah, I know a better one:
"let's gamble hey jumbo now shake your bum and do the rumble..."
This little tidbit is from the otherwise good song called "Gamble Rumble" by Move (I don't think it's used in anime at all)
Now Playing: "I've got a Lovely Bunch of Coconuts" - Merv Griffin
Yep, that song Zazu sings for scar in The Lion King
