"Large ego, small elsewhere"

“Large ego, small elsewhere,” Mark looked up from his book a bit confused at the sudden burst of giggling from all the girls in the room. “I don’t get it.” 

“You might want to go look at yourself in the mirror hun” 

“A full length one,” she paused, "Naked” 

“What? Don’t picture me naked.” 

“Just go do it.” Kari said. “You know you shouldn’t read out loud.” 

Mark frowned, he didn’t feel any different.  He left the book on the ground and went into the bathroom and looked at himself. “I don’t get it.” 

Of course, Mark’s ego had never been large.
