How I Spent My Strummer Vacation/Gags

Couch gag

 * Homer is on water skis, with the others on to him, as he ski-jumps over sharks; everybody lands on the couch, but the sharks bite off Homer's feet off-screen and feed on them. They watch TV with the family. (This couch gag references the term "jumped the shark", which describes a TV show that has reached its peak and has eventually declined in quality).
