The weekend away at "the cabin in the mountains" always gets me. I don't know anyone with a cabin in the mountains and nobody in a TV show ever seems to actually own one either, but someone (boss, parent, friend) is always letting them use one for the weekend.
If I did have a cabin in the mountains I certainly wouldn't let some accident prone glib idiots use it for the weekend (and invariably burn it down or suffer some other disaster), but that's just me.
