In a surprise move, Tami filled Bob's entire San Jose office at Colliers International with packing peanuts.

"I'm glad I was finally able to destroy Bob!" she says. "It's been long overdue."

Past pranks Bob has pulled on his family include putting cellophane on all the toilet seats in the house and removing all the toilet tissue, dying the milk green, and putting toilet tissue in his children's shoes.

Last year for April Fools' Day, he placed "For Sale" signs on the front lawn and sent a mass email to friends and co-workers about the family moving. He played it cool and let the joke ride out for several days. Tami says she got "bombarded with tons of phone calls from friends and folks from his office for two weeks."

Although home is a frequent place for trickery, co-worker and close friend Mark Zamudio says the office is another favorite place for Bob's pranks.

"He's the king of pranks," Zamudio says. "He's always been known to do them." Zamudio, who has worked at Colliers International in San Jose for 22 years, says that Bob has pulled tricks throughout his 18 years at the company. Although April Fools' Day is his specialty, Zamudio says it's not uncommon to have confetti spilling from the top of a doorway anytime during the week.

Bob has been known to put humorous fake license plates on friends' cars, as well as call them up pretending to be an IRS agent and providing them the number to the San Francisco Zoo as a return number.

According to Tami and Zamudio, one of the best stunts Bob pulled in the office was setting up a fax machine with a microphone attached to it. He put instructions on the machine that said it used new voice technology and to speak the numbers into the microphone instead of pressing any buttons. The note said that if the fax did not begin right away the user should speak more loudly. The end result was several employees screaming numbers into the mike to the amusement of Bob and several staff members that knew better than to use the fax machine.

"He is a great guy," Zamudio says. "He pulls more pranks on more people than anybody, and for him to be flooded with peanuts like that was great—the entire office was cracking up."

At first Bob thought it was his co-workers but was shocked to find out his wife was behind the successful prank.

"He is always so jovial, but when he saw his office, you could tell he was perplexed. He was probably asking himself, 'How the heck am I going to clean this up?' "

According to Tami, he is still working on it.
