When clicked on enough, Tassadar will make jokes about the large size of Warcraft shoulderpads.
He makes reference to units from StarCraft that are no longer available in Starcraft 2, and gets frustrated when the void ray is mentioned, a unit from Starcraft 2.
One of his quotes also breaks the fourth wall by mentioning Starcraft 1 directly, and how far videogames have advanced since then.

He will also say "Here's my number. Khala me maybe,", a reference to the song "Call Me Maybe" by Carly Rae Jepsen.
