At the end of the Lucky Channel segment in episode 5 of Lucky Star, Akira Kogami, raging because she won't be appearing in the main show despite the introduction of a new cute-little-girl-type character, says to her co-host Minoru Shiraishi:
"You know. Why don't we change Shiraishi Minoru's name to something else? Like Su-"
The segment then ends abruptly.
What, if anything, was this a reference to? What name did she intend on giving him? Googling the quote doesn't help, and I can't find it in the lists of references people have compiled for the series either.
