Farhampton - S8-E1
Character mistake: When Barney is telling his story to Quinn in a minute he says, "Ted and I stopped being friends, Ted got hit by a bus, we made up." Barney got hit by a bus, Ted got hit by another car. (00:12:10)
Character mistake: Marshall's whole career focus is saving the environment, so it's a poorly written character choice that he buys plastic glasses to avoid a dish-washing feud, boasting that they can just throw them away. (00:20:10)
Dowisetrepla - S3-E7
Character mistake: In the scene where Robin and Lily are talking in the kitchen, Robin makes a reference to Mount Waddington being the tallest mountain in Canada. The tallest mountain in Canada is actually Mount Logan.
Character mistake: When they see Robin on the news at the end she says "Metro 1 News" instead of "Metro News 1". (00:12:20)
Character mistake: In another episode it is revealed that Robin hates nicknames and reacts badly when she, or anyone else, is given a nickname. However, in this episode her and Marshall give each other nicknames, and she doesn't seem bothered at all.
Suggested correction: Alot of stuff can be recycled. He would simply recycle the used plastic.

You can recycle the plastic but you have to wash it first, defeating all the purpose of buying it in the first place.
