I very much enjoyed the episode about Duck Tape Definitely my favorite out of all the episodes I have seen, I would recommend trying to watch it if your haven't seen it.
I happen to be watching an episode now. Its the one about beating different kinds of alarms. It's definitely not my favorite, but interesting as always. Being someone who does not have cable I find myself watching it quite a bit. I have to say I really enjoyed the one where they tried to bulletproof a car with just phone books.
Mythbusters is usually quite entertaining, I remember an episode where they tested if phone books were good for bullet proofing cars. I am completely jealous of how much stuff they get to shoot and blow up, they have the most fun jobs ever.
It's very entertaining, because they do the most interesting things. Like trying to fold something more than 8 times. Or lifting a car off the ground with duct tape.
... resorted to tanks to pull them apart. Great episode.
I'd have a hard time picking a favorite. Tory smashing his face in the ground trying to jump a wagon with the bicycle always makes me laugh though.
Any episode where Adam makes some sort of walrus reference to Jamie, or Jamie does something entirely bad *** like the racing bike when they replicated the youtube video of pulling a tablecloth out from under a huge dining room table.
Or watching Grant get freaked out by bugs, like the 'cold feet' episode late last year, or the beer/liquor spinning chair of death that made him puke in like 3 seconds.
I love my tivo for playing things back slowly, especially when they play back a high-speed shot in slow motion and I can play it even slower. I love watching the shock waves of explosions.
Frankly though, this season seems to be more about busting the myth in 5 minutes, and then planning a way to blow the stuff up. It's still highly entertaining, though.
And let's not forget our Armor Games homage to MythBusters:
