There was a very brief but pretty decent moment of inflation in the latest Family Guy episode, Christmas Guy. Stewie tricks Meg into being bitten by a snake and she instantly balloons up. The actual inflation only lasts mere frames (you know what the animation's like) but I liked the way the end result looked.
Thank you, bootleggers. Here's the scene, just after the 4 minute mark at the dinner table:
