During each minute of a comedy show, Carlin laughs 555 times. Carlin watches 333 comedy shows every day, and each show is 404040 minutes long. How many times does Carlin laugh every day due to the comedy shows?

74,672,652,600. Take the time of the show and multiply it by the number of times she laughs in a minute. Then multiply that by the number of shows she watches in a day. That number seems pretty large though so you may want to make sure you have the right numbers and that it's not just 5 times, 3 shows, and 40 minutes.
