Apparently all that gum chewing and swallowing is no joke! In an August 2016 profile in the Washington Post, Spicer admitted to chewing and swallowing 35 pieces of gum a day -- before noon!
On Sunday, Spicer responded to the SNL skit, telling Extra that he "thought it was a 'really funny show,' but McCarthy could 'dial it back' a bit, adding that 'she needs to slow down on the gum chewing; way too many pieces in there.'" I think he just means pieces at one time. Maybe in real life, he swallows them one by one!
