I think Tenna slurps up entire sub sandwiches like noodles, and then whinges and complains about his employees making him fat before yelling at them to order more or else he'll fire them. He punches a wall and cries because Spammy used to call those sandwiches "hoagies" and they'd share them.

What if Tenna got sad while on his custom XL toilet and shrunk down and fell in the toilet and Mike had to fish him out
