Fun story about the 'name game': In a past job, I was responsible for supporting phone carrier acceptance testing for a major smartphone company. That meant I got to ride around in the test van - exactly like the "can you hear me now" guy from TV!
Except they didn't say "can you hear me now?" - they played a name game. Their version was a little different, though - they picked a popular franchise (Simpsons, Star Wars, etc.) and named one character per call, while the receptionist on the other end of the line had a master list of characters open on their computer.
"Hello?" "Moe" "Correct!" <click>
"Hello?" "Principal Skinner" "Correct!" <click>
This satisfied the technical requirement that a real conversation take place, while alleviating the crushing boredom of riding around rural North Carolina for hours on end making fifteen second phone calls...
Anyway, could be a nice alternative version to play in lines - pick a franchise and compete to name as many characters as you can, while a referee has IMDB open on their phone or tablet. It gets pretty challenging after a while!
