My boyfriend the nerd: Xmas special

It´s christmas eve and in spain, Nerd tells his friends that he meet the real Phineas and Ferb; their friends don´t believe him; They are a extrange group; One (Stan) acts as his name: like Stan the main character of American Dad (he is red) and hates Phineas and Ferb; Another friend is named "S" (his name is never given) and is a Baljeet lookalike (in physical and mind way), the other David is a dull boring boy

When noone believes nerd; he calls Phineas and Ferb and travel Danville again
