Rugrats, Season 1

[Cut back to the TV, where the fishing show breaks for a chicken commercial]

Chareen:
[on TV] Hi, I'm Chareen for Squeaky Chicken Restaurants. [cut back to Grandpa, who gets up from his chair to, shall we say, "take care of personal business"] Want to know what we got in store for you? Our new Chicken Half-Pounder!

Grandpa:
Well, nature beckons.

Chareen:
[voice only, on TV] The other guys only give you a third of a pound in their chicken sandwich, and, yeech, that's without Squeaky's special sauce. So come on in now and try our new Chicken Half-Pounder! It's more chickenny! And for a limited time only...

[As the commercial continues above, Tommy puts the spent toilet paper and the plunger aside. Grandpa, meanwhile, offstage, gets a surprise of his life]
