* The first game occasionally tricks you into jumping to the next screen... directly into a pool of water/lava.
* In the middle of Zoda's evil gloating, Mike jams bananas in his ears to drown him out. In the ending sequence of the second game a character mentions that he still has them in his ears.
-->'''Game:''' Your head is aching. You jam bananas in your ears.
* Three of the sealed caves that Mike can blast open in the Wild West contain giant chicken nuggets. They taste delicious!
* Several {{Non Player Character}}s comment on Mike's having bananas in his ears. This is also mentioned at the end of the sequel.
* In the second game's Prehistoric stage, the caveman tribe holds out hope on a prophecy of relief from the south. It turns out the prophecy specifically calls for a 'Southpaw Reliever,' a clear baseball reference. (A relief pitcher being the backup in case of injury, and southpaw being a baseball term for left handed.) Attempt to [[RefusalOfTheCall deny that you're the one]] has Mike state that he's ''right''-handed and a ''starting'' pitcher. The tribe elder just replies that [[ButThouMust they can change their lineup.]]
