"I Know an Old Lady" is a song about an old lady who swallows a fly, followed by a series of other creatures that she swallows to catch the fly (and subsequent creatures), but the singer does not know why she swallowed a fly.
This song was sung by Judy Collins in episode 205 of The Muppet Show, with a silhouette of an old lady who appeared to do what the song says. Commentary was provided by Statler and Waldorf. After the song, and after making their decision, Waldorf notes that he swallowed his gum, and Statler tells him "How very dumb to swallow your gum".
