contagious

sorry for posting so much tonight but i have too
i was watching some MCR interviews and every time they were being serious i would be serious and then tey would crack up laughingand even is i didn't get the joke i'd be laughing with them. it's like its almos contagious cos its really hard not to laugh when they laugh. does the same thing happen to you guys?
