Is there any explanation for "Tequila" in the Kuragehime eyecatch? Kuragehime has my favorite eyecatch of all the anime I've seen:

Kuragehime Eyecatch

It's very amusing, but the "tequila" is pretty irrelevant to the show. Tequila isn't in any way relevant to the plot. It seems to be just a random word that they chose to use.

Is there any explanation for why they say "tequila" in the eyecatch, or is it just a random non sequitur for comedic effect?
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.
