- Texiera's version of Ashir wears armor.
- Is Ashir really hitting on Tara right in front of Morgan?
- Again we get a reference to Shakira's familiarity with Skartaris' past.
The title of this issue relates to a ubiqitous phrase of the seventies--particularly when associated with the smiley face. Wikipedia has an overview here. Morgan's knowledge of the classic smiley and its association with the phrase is an anachronism given that he's been in Skartaris since the sixties. Bernard and Murray Spain didn't put the two together on various novelties until 1972. Maybe he saw it on his brief visit to Machu Picchu?
The history of the smiley face as a symbol is also well-covered on Wikipedia--though no mention is made of Trojan smilies.
Morgan's trick is, of course, inspired by the Trojan horse used by the Greeks during the seige of Troy in Homer's Illiad. Besides the shape of wooden device being different, Morgan also (wisely) chooses not to climb inside his Trojan Smiley.
The Trojan rabbit sequence from Monty Python and the Holy Grail also gets referenced. Texiera's rendition of the guardsman who first sights the smiley face looks a fair bit like the taunting French knight from that film.
