The Eleventh Doctor spoke an alien language while fixing the TARDIS translation matrix. When Alice Obiefune didn't understand him, he repeated, "We'll have the translation matrix fixed in a jiffy" in English. (COMIC: The Lost Dimension ^[+]Loading...["The Lost Dimension (comic story)"])

Behind the scenes

The alien text is written in the lowercase version of the font Gobbledygook. The text actually reads, "A stream of unintelligible dingbats, an alien language".
