Continuity mistake: The two CIA guys are watching the softball game and report the it is the bottom of the ninth - the Senators are winning. In the next scene the Senators are batting. If the Senators are winning why are they batting?
Other mistake: When Morris is chasing the ambulance on his bicycle, he gets pushed/bumped towards the picnic table. As he tumbles over the table into the water you can see handle bars attached to the bicycle, however whilst Morris is flying through the air (separately to the bicycle), he is holding a second set of handle bars in his hands.
