(Strip Number 967, Original Publication Date, 26 October 1985)
Panel 1: As Michael shows off his 3 Mad Scientists' Amazing Talking Head costume, Elly asks him how the heck he's supposed to dance in that dime-store Davros costume.
Panel 2: Elly follows that by asking him other questions he should have asked Brian and the boys because she can't see how he's supposed to eat, drink or sit down.
Panel 3: She doubts that he can even fit through the doorway in the rig-up he got swindled into wearing.
Panel 4: Since Mike would rather look cool than be comfortable, he breezily comments on how he considers these insignificant details.
Summary: Given that Lynn cheerfully alludes to having pulled the costume idea out of her arse, my guess is that she's using this to respond to criticism about how impractical the concept is. Five bucks says that if we had a camera in Lynn's house, we'd have seen either Ruth, Rod, Tom or Aaron ask her the questions Elly's asking Michael only to get the same stupid answer.
