Tuff Gum

Tuff Gum is a jingle in the Season 2 episode "Suddenly Suzy" as part of the advertisement promoting Tuff Gum.

Lyrics
Phineas: What's that grinding sound?''' Buford': Tuff Gum! Like the song says...''

Male Singer: Pound nerds like a drum

Stop a train with your thumb

It's Tuff Gum!

Phineas: Wow, can I have some?

Buford: ''Nah, I don't think so. It's for bullies only.''

Phineas: Hey Ferb, you got any regular gum?

Male Singer: Regular gum!

Background Information

 * The teen who is beating up the boy was the same "local bully" that almost ate Biff in "Voyage to the Bottom of Buford". Evidently, he patronizes Tuff Gum.
 * The logo for Tuff Gum is similar in appearance to the Pokémon, Geodude.
 * The description on the wrapper says "For guys who can't spell". One may note that this motto is present because of the word "Tough" being spelled wrong.

Victory Gum
Victory Gum is a similar jingle from the movie "Phineas and Ferb The Movie: Across the 2nd Dimension". It is used to promote the Victory Gum that Buford chews on. The product along with its jingle are very similar to that of Tuff Gum. The motto on the wrapper is "Even if you win by forfeiture".

Trivia
In the song Snacks, Linda Flynn-Fletcher mentions Tuff Gum.
