MacGyver extinguishes the thermite torch (used to open the armoured car) by pushing the end into the dirt. This wouldn’t work as thermite reactions use the oxygen from the metal oxide, not the air.

When Mac gets the R/C plan down in the diner his shirt is dark green with chinese type coller. When he runs outside with the plane his shirt has suddenly changed to a light gray shirt with normal coller.

In the scene where MacGyver's making the fertilizer bombs, we see him take the engine start can off the shelf and put it on the bench.

Then when he goes to use it.. we see the exact same shot again as he takes it off the shelf again.

We can clearly see it on the bench during the "in between" shots.

Now we all know Rocky has he's viewing schedule on a two month interval.

*checks watch* next nitpick scheduled.... March 11th

Rocky, that sounds like a continuity issue with the editing. I've noticed that with several MacGyver episodes. It looks like it's two different takes, and the film editors just didn't catch it!

I think he wore that same shirt (the greyish-greenish one with the high collar) the entire first season. They must've bought 20 of 'em so he's always have a freshly laundered one. Trying to establish Mac's image while on a budget... never knowing if the show was gonna be canceled or go on to a second season. At least he got some new shirts after that.

Are you saying continuity issues don't count as nit picks? or just saying?

When Mac assembly the torch, is thicker and rustier than when he uses it...

When they are in the freezer, he puts the cardboard tube into the door. Then when he is getting the metal poe to hook it up near the lightbulb, you can see the door and there is no cardboard sticking from it. Then we see him hook his contraption up and the cardboard magically reappears.

Not exactly a nitpick but when Mac and Dave are having the conversation while digging the hole, Dave tells Mac what he's been through as a POW and that he was digging his own grave once which resulted in his humiliation instead of his death.

In the conversation Dave says: 'I know what that sounds like.'
Mac replies with: 'Just the truth.'
After that phrase Dave's watch bleeps. It's just a single bleep as when you would start pushing the buttons on your watch.

Listen carefully though. A quick single bleep. Could've been 8, 9, 10 a.m.

Besides you could clearly see their watches while digging and Dave was wearing a digital watch.

Curse that hourly chime function!
