Is there any explanation for "Tequila" in the Kuragehime eyecatch?
Although it can't really be confirmed ( or has not been confirmed yet ) 


  It's a reference to a song from the 70's, which was mostly instrumental but contained one single lyric repeated throughout: "tequila." I guess the style was similar enough to the miniature music bit in that eyecatch to make the reference clear to everybody old enough to get it.

Not sure which tequilla song they reffer to as there are about 20.
