Expect some big laughs when The Big Bang Theory“s Jim Parsons makes his debut as SNL host this Saturday.

In a series of promos for this week’s show, Parsons relentlessly goofs on SNL cast-member Bobby Moynahan with the help of a handy laugh track, out-maneuvers one of Bobby’s pranks and attempts to explain what “Bazinga”; means.

You can catch Jim Parsons and musical guest Beck on this week’s edition of SNL, airing Saturday, Mar. 1, at 11:35 p.m. EST/PST on Global.
