Okay, I am well aware that Kid vs. Kat is leading in my poll. However, this was created specifically for my FF friend, elaine30432. She doesn't know Kid vs. Kat. So I made this a Johnny Test crossover.
Johnny strolled into his family's kitchen, to see his family already at the table. He took his seat.
"Kids, your cousins, the Flynn-Fletcher family is coming over today!" his dad said.
"Do they have kids MY age?" Johnny asked suspiciously.
"Two, Phineas and Ferb" his mom said. Johnny cheered. Susan smiled at her little brother's enthusiasm.
She knew it was wrong, but she was madly in love with Johnny. She was so scared, if she told someone, especially Johnny, she would be ridiculed for life. So she tried her hardest to keep it a secret.
"Wonder if we could perform some tests on them?" Mary said with a mischievous glint in her eyes.
Meanwhile…Phineas walked into the kitchen as soon as he was finished packing.
"Morning, Phin" his mother, Linda said. Phineas smiled.
"Morning mom" he said. He looked at his stepbrother, and lost himself in thought.
'Mom says our cousins are geniuses, hopefully they'll have something to cure this… feeling' he thought.
"Phin, what do you want to eat?" his mother asked, snapping him out of his thoughts.
"Oh, I'm not hungry" he said.
"Well, everyone else is done eating, so let's hit the road!" his father, Lawrence said.
