show me the money: a two-part play

scene 1
mummy is typing away on her computer in the study.
at her desk is an open magazine that happens to be open at the page where a picture of the following lego police station playset is advertised:
act 1 scene 1
james walks into the study and immediately spots said picture of lego police station playset
james: (jabbing finger at police motorbike, car and paddy wagon) mummy, i want this, this and this!
mummy: (absent-mindedly working on computer and not paying full attention to james) hmmmm? what? yes dear, of course you want it. so would i. but it's too expensive mate, it's like $140! i don't have that kind of money!
james continues to jump around in the study and plays with things he shouldn't as usual, then after a matter of minutes, walks out of the study. mummy is rather relieved with the peace and quiet from his departure.

act 2 scene 1
james comes running into the study, mummy is still absent-mindedly on the computer only half paying attention to him
james: mummy, mummy, can you open this for me?
mummy: huh? what? oh? ok. (mummy unscrews the bottom of his piggy bank container without even realising what she is doing.)
james: (proceeding to fling all his token coins from grandma and grandpa out of his piggy bank onto mummy's desk then shouts triumphantly) here's my money mummy!!!!
mummy: huh?? hoi! what the...?? why are you throwing the coins about and making a mess??

...and then it dawns upon mummy what has actually happened!!!!!!!
the boy had put 10 cents and 10 cents together and came up with what he thought was equivalent to $140!
mummy is speechless for a second and doesn't know whether to laugh or cry at his innocent, innocuous yet strangely logical and train of (calculating) thought...
do we have a little donald trump in the makings? we certainly hope not!!!!!!!!!!!
